Texas Instruments  TSU6111RSVR

The TSU6111 is a differential high performance automated SP2T switch with impedance detection. The switch features impedance detection which supports the detection of various accessories that are attached through DP, DM and ID. The charger detection satisfies USB charger specification v1.1. VBUS_IN has 28V tolerance to avoid external protection.

Power for this device is supplied through VBAT of the system or through VBUS_IN when attached.

The switch is controlled by automatic detection logic or through I2C manually. JIG and BOOT pins are used when a USB, UART JIG cable is used to test in the development and manufacturing. TSU6111 has open-drain JIG output (active low).
