This article introduces USB OTG controllers and power management devices from Texas Instruments (TI), which can add full-speed USB OTG functionality to platforms in small-size, low-power designs. They can be easily connected to TI's OMAP processors and many other DSPs, and solve the problem of USB direct connection and power management complexity. USB OTG enables connectivity between portable consumer electronic devices and eliminates the need to find a bulky PC host to transfer pictures, music, and data.
The document discusses the benefits and specifications of High-Speed USB OTG, which allows portable consumer electronic devices to connect directly without a PC host. It addresses power management complexities and introduces new mini/micro connectors for smaller form factors.
Texas Instruments presents the TUSB60xx family as a solution for application processors (DSPs, OMAP, MCUs) lacking integrated USB cores. These devices act as bridges between the USB 2.0 high-speed bus and local processor interfaces, supporting host, peripheral, or full OTG modes.
USB OTG is an addendum to the USB 2.0 specification that defines a new class of devices extending peripheral functionality to include limited host capabilities.
The TUSB60xx family enables application processors without integrated USB cores to function as high-speed peripherals, embedded hosts, or full OTG devices.
