All versions of USB specify cable properties; version 3.X cables include additional data paths. A self-powered hub is a device that provides high-power ports. This may cause problems with some computers, such as drawing too much current and damaging circuitry. The maximum allowed cross-section of the overmold boot (which is part of the connector used for its handling) is 16 by 8 mm (0.63 by 0.31 in) for the standard-A plug type, while for the type-B it is 11.5 by 10.5 mm (0.45 by 0.41 in).[2]. [57][67][68], As of April 2016[update], there are silicon controllers available from several sources such as TI and Cypress. 57 It’s a horizontal port with the “bottom” portion dedicated to pin connectors. As of USB Power Delivery specification revision 2.0, version 1.2, the six fixed power profiles for power sources have been deprecated. Devices' configuration and low-power functions must operate down to 4.40 V at the hub port by USB 2.0 and that devices' configuration, low-power, and high-power functions must operate down to 4.00 V at the device port by USB 3.0. The female connector mounted on the host or device is called the receptacle, and the male connector attached to the cable is called the plug. USB 3.0 introduced Type-A SuperSpeed plugs and receptacles as well as micro-sized Type-B SuperSpeed plugs and receptacles. Charging ports on a host with both kinds will be labelled. And the OTG cable I have it front of me has a Micro … This creates the infamous one-sided USB connection that only works when the cable is insert… USB 2.0 provides for a maximum cable length of 5 meters (16 ft 5 in) for devices running at high speed (480 Mbit/s). The data pins in the standard plugs are recessed compared to the power pins, so that the device can power up before establishing a data connection. [49][50], Per the base specification, any device attached to a standard downstream port (SDP) must initially be a low-power device, with high-power mode contingent on later USB configuration by the host. Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports draw from the hub's self-power. The modes are configured using VDMs through the configuration channel. USB plugs fit one receptacle with notable exceptions for USB On-The-Go "AB" support and the general backward compatibility of USB 3.0 as shown. An OTG product must have a single micro-AB receptacle and no other USB receptacles. Battery Charging Specification 1.1 specifies that charging devices must dynamically limit bus power current draw during High Speed signaling;[51] 1.2 specifies that charging devices and ports must be designed to tolerate the higher ground voltage difference in High Speed signaling. Micro USB Micro USBs are another miniaturized version of USB interfaces. The USB standard specifies tolerances for compliant USB connectors to minimize physical incompatibilities in connectors from different vendors. If an application on the B-device requires the role of host, then the Host Negotiation Protocol (HNP) is used to temporarily transfer the host role to the B-device. [39] The USB 2.0 specification requires that cable delay be less than 5.2 ns/m (1.6 ns/ft), (192000 km/s) - which is close to the maximum achievable transmission speed for standard copper wire). The initial versions of the USB standard specified connectors that were easy to use and that would have acceptable life spans; revisions of the standard added smaller connectors useful for compact portable devices. [76], Prior to Power Delivery, mobile phone vendors used custom protocols to exceed the 7.5 W cap on USB-BCS. The modes have differing hardware and cabling requirements. We plug in every device we have to chase the dream", "Charge All Your Devices Using the Anker PowerPort+ 5 USB-C with USB Power Delivery", "Belkin® Launches USB-C Car Charger + Cable With Power Delivery", "Belkin USB-C Car Charger + Cable – The World's First Car Charger with Power Delivery Goes the Distance", "USB-IF Introduces Fast Charging to Expand its Certified USB Charger Initiative", "How fast can a fast-charging phone charge if a fast-charging phone can charge really fast? The Micro-AB receptacle is capable of accepting both Micro-A and Micro-B plugs, attached to any of the legal cables and adapters as defined in revision 1.01 of the Micro-USB specification. To fully grasp what exactly a micro-USB is, you’ve got to first understand the name “USB.” USB stands for a Universal Serial Bus, and you may very well be more familiar with USB-A ports, which are the USB ports that come standard on many laptops and computers. The OTG device with the A-plug inserted is called the A-device and is responsible for powering the USB interface when required, and by default assumes the role of host. [15][18] The Micro connector is also designed to reduce the mechanical wear on the device; instead the easier-to-replace cable is designed to bear the mechanical wear of connection and disconnection. Magnetic connectors were developed mainly for mobile phones devices having Micro B, USB-C or Apple's Lightning ports . The small size of Micro USBs allowed manufacturers to produce slimmer devices. SanDisk - Ultra 128GB USB 3.1, USB … First of all, it’s important to understand what exactly a USB connector type is. Alternate Mode dedicates some of the physical wires in the USB-C cable for direct device-to-host transmission of alternate data protocols. Micro USB to USB A Adapter, 2 Pack USB A (Male) to Micro USB (Female) Convertor Adapter Compatible with Android Phone, Tablets and More. However, some of this directed topology is lost with the advent of multi-purpose USB connections (such as USB On-The-Go in smartphones, and USB-powered Wi-Fi routers), which require A-to-A, B-to-B, and sometimes Y/splitter cables. USB 2.0 A Male to Micro B 5 Pin Left Angled 90 degree Male Cable Lead, Micro USB Cable Android Charger, High Speed USB to Micro USB Cable, USB 2.0 A Male to Micro B Male, USB … The pinout diagram for the micro USB type-B very similar to USB type-A except for the last two pins 4 and 5.

It replaces other connection types as of USB 3.2 onwards. Similar to standard USBs, … Micro-A adapters allow for connection to standard-A plugs, as used on fixed or standard devices. Mini and micro connectors have their GND connections moved from pin #4 to pin #5, while their pin #4 serves as an ID pin for the On-The-Go host/client identification.[7]. For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. Compliant devices must either fit within the size restrictions or support a compliant extension cable that does. These are usually called USB decorations. Low-power devices may draw at most 1 unit load, and all devices must act as low-power devices before they are configured. Otherwise, connecting a device could cause problems with the host's internal power. This USB power meter additionally provides a charge readout (in mAh) and data logging. Micro-USB was endorsed as the standard connector for data and power on mobile devices by the cellular phone carrier group Open Mobile Terminal Platform (OMTP) in 2007. USB cables exist with various combinations of plugs on each end of the cable, as displayed below in the USB cables matrix. [89][90], The GSM Association (GSMA) followed suit on 17 February 2009,[91][92][93][94] and on 22 April 2009, this was further endorsed by the CTIA – The Wireless Association,[95] with the International Telecommunication Union (ITU) announcing on 22 October 2009 that it had also embraced the Universal Charging Solution as its "energy-efficient one-charger-fits-all new mobile phone solution," and added: "Based on the Micro-USB interface, UCS chargers will also include a 4-star or higher efficiency rating—up to three times more energy-efficient than an unrated charger. Get it as soon as Tue, Dec 1. Y-shaped USB 3.0 cable; with such a cable, a device can draw power from two USB ports simultaneously. There are five speeds for USB data transfer: Low Speed, Full Speed, High Speed (from version 2.0 of the specification), SuperSpeed(from version 3.0), and SuperSpeed+ (from version 3.1).

The different A and B plugs prevent accidentally connecting two power sources. A micro-USB is a [27] The USB-C plug connects to both hosts and devices, replacing various Type-A and Type-B connectors and cables with a standard meant to be future-proof. [53] Barnes & Noble Nook Color devices also require a special charger that runs at 1.9 amperes.[103]. Toshiba calls it USB Sleep-and-Charge. The Micro USB was developed to standardize and streamline phone charging devices. Both Mini-A and Mini-B plugs are approximately 3 by 7 mm (0.12 by 0.28 in). [60][61] The standard is designed to coexist with the previous USB Battery Charging specification.[62]. Micro-A plugs, Micro-B plugs, and standard cables will also be available. The Micro-USB interface is commonly found on chargers for mobile phones. GE 3 ft. USB Micro, Mini Combo Cable with Adapter.

USB “Type A” connections refer to the physical design of the USB port. In Europe, micro-USB became the defined common external power supply (EPS) for use with smartphones sold in the EU,[21] and 14 of the world's largest mobile phone manufacturers signed the EU's common EPS Memorandum of Understanding (MoU). In some sources D+ and D− are erroneously swapped. The Micro plug design is rated for at least 10,000 connect-disconnect cycles, which is more than the Mini plug design. 2.0) has been released as part of the USB 3.1 suite. Related Searches. Devices can request higher currents and supply voltages from compliant hosts – up to 2 A at 5 V (for a power consumption of up to 10 W), and optionally up to 3 A or 5 A at either 12 V (36 W or 60 W) or 20 V (60 W or 100 W). [33] Some manufacturers such as Apple provide proprietary cables that permit their devices to physically connect to a USB standard port. 1), an extension that specifies using certified PD aware USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5 W) to devices with greater power demands. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this. (In the past, before the development of Micro-USB, On-The-Go devices used Mini-AB receptacles). Where devices (for example, high-speed disk drives) require more power than a high-power device can draw,[46] they function erratically, if at all, from bus power of a single port. [citation needed] Examples include USB-powered keyboard lights, fans, mug coolers and heaters, battery chargers, miniature vacuum cleaners, and even miniature lava lamps. The charging port must not apply current limiting below 0.5 A, and must not shut down below 1.5 A or before the voltage drops to 2 V.[49]. In a charge-only cable, the data wires are shorted at the device end, otherwise the device may reject the charger as unsuitable. That’s it for the so-called “standard” ports, but there are … However, USB 2.0 hosts may use the USB 3.0 port, but it can’t use the features of the USB 3.0 like having a faster transfer rate. On the device side, a modified Micro-B plug (Micro-B SuperSpeed) is used to cater for the five additional pins required to achieve the USB 3.0 features (USB-C plug can also be used). [66] USB PD Power Rules replace power profiles, defining four normative voltage levels at 5 V, 9 V, 15 V, and 20 V. Instead of six fixed profiles, power supplies may support any maximum source output power from 0.5 W to 100 W. The USB Power Delivery specification revision 3.0 defines a programmable power supply (PPS) protocol that allows granular control over VBUS power in 20 mV steps to facilitate constant current or constant voltage charging. [79] On laptops, charging devices from the USB port when it is not being powered from AC drains the laptop battery; most laptops have a facility to stop charging if their own battery charge level gets too low. To allow for voltage drops, the voltage at the hub port is specified in the range 4.40–5.25 V by USB 2.0, and 4.45–5.25 V[41][not specific enough to verify] by USB 3.0. USB connector types multiplied as the specification progressed. Only downstream facing ports provide power; this topology was chosen to easily prevent electrical overloads and damaged equipment. Modes are identified by their names and icons, and the specification suggests that plugs and receptacles be colour-coded (SuperSpeed is identified by blue). USB provides for these devices as being self-powered. Manufacturers of personal electronic devices might not include a USB standard connector on their product for technical or marketing reasons. USB has been selected as the standard charging format for many mobile phones, reducing the proliferation of proprietary chargers. However, such devices may come with a Y-shaped cable that has two USB plugs (one for power and data, the other for only power), so as to draw power as two devices. Australian and New Zealand power socket with USB charger socket. It draws 1 unit load for the hub controller and 1 unit load for each of at most 4 ports. Micro-USB B offers a connection physically smaller in size to a USB … It can be found in many devices like mobile phones, cameras. Charging docks supply power and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. PoweredUSB is a proprietary extension that adds four additional pins supplying up to 6 A at 5 V, 12 V, or 24 V. It is commonly used in point of sale systems to power peripherals such as barcode readers, credit card terminals, and printers. Revision 1.2 of the specification was released in 2010. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data paths. Portable devices having a USB On-The-Go port may want to charge and access USB peripheral at the same time, but having only a single port (both due to On-The-Go and space requirement) prevents this. USB cables have plugs, and the corresponding receptacles are on the computers or electronic devices. [1] The USB-C plug however is reversible. A variety of USB cables, including micro-USB, mini-USB, and standard USB. Some non-standard USB devices use the 5 V power supply without participating in a proper USB network, which negotiates power draw with the host interface. Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is for power and data transfer, the other solely for power, which makes the device a non-standard USB device. The mini and micro formats also provide for USB On-The-Go with a hermaphroditic AB receptacle, which accepts either an A or a B plug. $6.99$6.99. Quickview. SuperSpeed uses separate transmit and receive differential pairs, which additionally require shielding (typically, shielded twisted pair but twinax is also mentioned by the specification). [56][63][64] It covers the USB-C cable and connector with four power/ground pairs and a separate configuration channel, which now hosts a DC coupled low-frequency BMC-coded data channel that reduces the possibilities for RF interference. Micro-A is apparently similar to the standard Micro-B plug, but without chamfered corners: A Micro-AB receptacle is also rectangular. [8], The thinner Micro-USB connectors were intended to replace the Mini connectors in devices manufactured since May 2007, including smartphones, personal digital assistants, and cameras.[17]. [72] [73][74][75], On 8 January 2018 USB-IF announced "Certified USB Fast Charger" logo for chargers that use "Programmable Power Supply" (PPS) protocol from the USB Power Delivery 3.0 specification. This connector … [29][30] Type-A and Type-B adaptors and cables are required for older devices to plug into USB-C hosts. 2.0 at multiple voltages. Some devices, when plugged into charging ports, draw even more power (10 watts at 2.1 amperes) than the Battery Charging Specification allows — The iPad is one such device;[102] it negotiates the current pull with data pin voltages.

[53] When D+ = 2.8 V and D− = 2.0 V, the device may pull up to 2 A of current.[54]. USB Type-A. [81] Dell calls this feature PowerShare,[82] and it needs to be enabled in the BIOS. [13] Mini-B connectors are still supported, but are not On-The-Go-compliant;[14] the Mini-B USB connector was standard for transferring data to and from the early smartphones and PDAs. Multi-lane SuperSpeed (USB 3.2 Gen x2) device. All current OTG devices are required to have one, and only one, USB connector: a Micro-AB receptacle. [citation needed] On Dell, HP and Toshiba laptops, the port is marked with the standard USB symbol with an added lightning bolt or battery icon on the right side. [1] The official USB specification documents also periodically define the term male to represent the plug, and female to represent the receptacle.[2]. Micro Center is passionate about providing product expertise and exceptional customer service at each of our locations. [52], Before the Battery Charging Specification was defined, there was no standardized way for the portable device to inquire how much current was available. In addition to limiting the total average power used by the device, the USB specification limits the inrush current (i.e., the current used to charge decoupling and filter capacitors) when the device is first connected. This ID pin is connected to GND in Type-A plugs, and left unconnected in Type-B plugs. Also, it is the same for micro USB type-a and micro USB type-b. Unlike other data buses (such as Ethernet), USB connections are directed; a host device has "downstream" facing ports that connect to the "upstream" ports of devices.
