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.
