产品描述

The TSU5511 is designed to interface the cell 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 State Machine for details). It will then switch to the appropriate channel—data, audio, or UART.

The TSU5511 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.
