OTG Full Form

What is the full form of OTG?

On-The-Go is the full form for OTG. OTG is a Universal Serial Bus (USB) standard that enables the connection of USB devices. It enables USB gadgets such as tablets or smart devices to operate as hosts, allowing other USB devices such as a digital camera, mouse, or keyboard to be connected. This enables USB OTG gadgets to communicate with one another without the need for a Personal computer (PC). To use this feature, your device must support OTG Host; only then can you plug an OTG connector into your phone and sync your phone to a USB device to transmit data.

Roles Of OTG

USB OTG assigns devices two roles:

  • A-device OTG: An OTG A-device is also referred to as a power supply.

  • B-device OTG: An OTG B-device consumes power.

This helps to define which side of the link supplies power and which serves as the host. The A-device operates as a USB host in the standard link setup, while the B-device serves as just a USB peripheral. Later, the host, as well as peripheral modes, can be swapped using the Host Negotiation Protocol (HNP).

Uses Of OTG Specification

The following are the uses:

  • A USB OTG link allows you to connect your tablet or mobile device to a USB device, mouse, controller, webcam, or any other smart device.

  • There are also OTG centre points that allow you to plug your phone into multiple gadgets.

  • When producing reports with a terminal on your system, or transferring programs from one smartphone to another, an OTG link comes in handy.

Types Of OTG Cable Plugs

Mini OTG plugs

The first OTG specification had a mini-AB plug receptacle. The mini A type allows you to connect to a Standard A USB port in the accessories. The device becomes an OTG A device when a mini A type is inserted. Similarly when an OTG B is connected the device becomes a mini B type.

Micro OTG plugs

The mini OTG plug was later replaced by Micro OTG plugs. The Micro AB was the most accepted one which can take both Micro-A and B types. This OTG plug was able to take the position of all other USB receptacles and became the most widely used. One end of this cable act as a micro-A plug and the other as a micro-B plug.
