DESCRIPTION
The TS5USBA43402 is designed to interface the cellphone 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 State Machine for details).
It will then switch to the appropriate channel—data, audio, or UART.
The TS5USBA43402 has an I2C interface for communication with the cellphone 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.
