Low Quiescent Current Load Switch

The XC8101 series is a low On resistance line switch IC with ON/OFF control 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/OF 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 connected to the output pin during in the stand-by mode, the internal switch between the VOUT and VSS of the XC8101 enables the electric charge in the load capacitor to be discharged. Because of this discharge function, the VOUT pin voltage falls quickly to VSS level.

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.
