XC8102
Series
Load Switch with Low On-Resistance
ETR2502-006a
■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 V
OUT
pin voltage falls quickly to the V
SS
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.
