XC8102

XC8102 Series Load Switch with Low On-Resistance (Current Limit 400mA) ETR25002-013b ■GENERAL DESCRIPTION The XC8102 series is a low ON resistance load switch IC with ON/OFF control and output current protection which integrates a P-channel MOSFET. By connecting the XC8102 to the output pin of a step-down DC/DC converter, the CE pin controls ON/OFF for each distribution switch to deliver power per requirements and maximize total power efficiency. As a result, the XC8102 helps to extend battery life and product operation time. The series contains a current limit and protection circuit so these are not required externally unlike discrete circuit solutions where MOSFETs and resistors are used. When a low signal is input to the CE pin, the series enters stand-by mode. Even where a load capacitor is connected to the output pin during stand-by, the electric charge stored at the load capacitor is discharged through the internal switch. As a result, the VOUT pin voltage falls quickly to the VSS level. The series contains over current protection with fold-back current circuitry which operates as over current protection and short circuit protection for the output pin. ■APPLICATIONS ● Smart phones / Mobile phones ● Digital still cameras / Camcorders ● Portable game consoles ■FEATURES On Resistance Input Voltage Range Power Consumption Stand-by Current Protection Circuit ON/OFF Function : 0.28Ω@ VIN=6.0V (TYP.) 0.31Ω@ VIN=4.0V (TYP.) 0.35Ω@ VIN=2.9V (TYP.) 0.52Ω@ VIN=1.8V (TYP.) 0....
