The TSU6111A is a high performance differential autonomous SP2T switch with impedance detection. The switch supports the detection of various accessories that are attached through DP, DM, and ID. The charger detection satisfies USB charger specification v1.1 and VBUS_IN has a 28V tolerance to eliminate the need for external protection. Power for this device is supplied through VBAT of the system or throughVBUS_IN when attached to a charger.

The SP2T switch is controlled by the automatic detection logic or through manual configuration of the I2C. JIG and BOOT pins are used when a USB or UART JIG cable is used to test the device in the development and manufacturing. TSU6111A has open-drain JIG output (active low).
