3 Description

The TSU8111 is a dual single-pole double-throw

(SP2T) micro-USB switch with an integrated linear

charger. The integrated charger eliminates the need for an external charger IC, reducing cost and board

space. The device operates from either a USB port or

dedicated charger and supports charging currents of

up to 950 mA. Power for the device is supplied

through VBAT or through VBUS when attached. The

TSU8111 detects BCv1.1-compatible chargers as

well as accessories that use an ID resistor. The USB

switch matrix can be controlled either by automatic

detection or manually through I2C.
