■ GENERAL DESCRIPTION

The XC8101 series is a low supply current line switch IC with ON/OFF control and output current protection which integrates

P-channel MOSFET. The XC8101 is suited for power distribution switch. With connecting to the output pin of step-down DC/DC

converters, the CE pin controls ON/OFF for each distribution switch to deliver power per requirements and maximize total

power efficiency. As result, the XC8101 helps extend battery life and product operation time. The XC8101 is available in an

ultra small package USP-4 and does not require any external capacitors so that it can provide small power unit design and

board space saving. When low signal is input to the CE pin, the XC8101 enters stand-by mode. Even where a load capacitor is

The XC8101 contains an over current protection with foldback current circuitry which operates as over current protection and

short circuit protection for the output pin.
