Description

The TSU5611 is designed to interface the cellular phone UART, USB, and audio chips with external peripherals via a micro-USB connector. The switch features impedance detection for identification of various accessories that are attached through DP and DM of the micro-USB port. When an accessory is plugged into the micro-USB port, the switch uses a detection mechanism to identify the accessory (see the State Machine for details). It will then switch to the appropriate channel–data, audio, or UART.

The TSU5611 has an I2C interface for communication with the cellular phone baseband or applications processor. An interrupt is generated when anything plugged into the micro-USB is detected. Another interrupt is generated when the device is unplugged.
