具有阻抗检测微型USB开关DP3T交换机支持USB ， UART ，音频和充电器检测 DP3T SWITCH WITH IMPEDANCE DETECTION MICRO-USB SWITCH TO SUPPORT USB, UART, AUDIO, AND CHARGER DETECTION
DESCRIPON
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.
