Micro-USB was embraced as the "Universal Charging Solution" by the International Telecommunication Union (ITU) in October 2009. Portable devices having a USB On-The-Go port may want to charge and access a USB peripheral simultaneously, yet having only a single port (both due to On-The-Go and space requirement) prevents this. OTG non-standard Commonly available "OTG" cables that address widespread misuse of Micro-B and Mini-B receptacles for OTG devices, e.

mode), two "sideband use" pins, V CONN +5V power for active cables, and a configuration pin for cable orientation detection and dedicated biphase mark code (BMC) configuration data channel. Apple, one of the original MoU signers, makes Micro-USB adapters available—as permitted in the Common EPS MoU—for its iPhones equipped with Apple's proprietary 30-pin dock connector or (later) Lightning connector. When a device doesn't recognize the faster-charging standard, generally the device and the charger fall back to the USB battery-charging standard of 5V at 1.Mini USB cables have been widely used for connecting and powering various electronic devices, including sat nav systems and radio scanners.

To accomplish this, a locking device was added and the leaf-spring was moved from the jack to the plug, so that the most-stressed part is on the cable side of the connection. USB ports and connectors are often color-coded to distinguish their different functions and USB versions. Because, again, my Mini A plug looks exactly identical to a Mini B plug except for its white-colored plate inside. 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.This is because USB is hot-swappable, and the connectors would be used more frequently, and perhaps with less care, than previous connectors. data (though only one pair is implemented in a USB-C cable), four pairs for SuperSpeed data bus (only two pairs are used in USB 3.

Micro-USB connectors, which were announced by the USB-IF on January 4, 2007, [13] [14] have a similar width to Mini-USB, but approximately half the thickness, enabling their integration into thinner portable devices. All current OTG devices are required to have one, and only one, USB connector: a Micro-AB receptacle.e., the current used to charge decoupling and filter capacitors) when the device is first connected. USB Battery Charging ( BC) defines a charging port, which may be a charging downstream port (CDP), with data, or a dedicated charging port (DCP) without data. USB-PD A and B plugs have a mechanical mark while Micro plugs have a resistor or capacitor attached to the ID pin indicating the cable capability. To allow for voltage drops, the voltage at the host port, hub port, and device are specified to be at least 4. On some devices, the Type-B receptacle has no data connections, being used solely for accepting power from the upstream device.
