The TSU8111 is a differential high performance automated SP2T switch with impedance detection and integrated Li-Ion linear charger device targeted at space-limited portable applications. 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 has 28V tolerance to avoid external protection. The device operates from either a USB port or dedicated charger and supports charge currents up to 950mA. Power for this device is supplied through VBAT of the system or through VBUS 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. TSU8111 has open-drain JIG output (active low).
