具有阻抗检测微型USB开关SP4T交换机支持USB ， UART ，音频和视频 SP4T SWITCH WITH IMPEDANCE DETECTION MICRO-USB SWITCH TO SUPPORT USB, UART, AUDIO, AND VIDEO
The TSU6712 is a multiple SP4T switch with impedance detection. The switch features impedance detection, which supports the detection of various accessories that are attached through DP and DM. The detection is based on the impedance values of the accessories as defined in Table 1. The TSU6712 is fully controlled using I2C and enables USB data, stereo and mono audio, video, microphone, and UART data to use a common connector port.
Power for this device is supplied through VBAT of the system or through VBUS when attached. The switch can be controlled through I2C. JIG and BOOT pins are used when a USB, UART JIG cable is used to test during development and manufacturing.
