85mΩ High Function Power Switch

■

GENERAL DESCRIPTION

The XC8108 series is a P-channel MOSFET power switch IC with a low ON resistance. A current limit, reverse current

incorporated as protective functions. A flag function monitors the power switch status. The flag output has N-channel open

drain structure, and outputs Low level signal while over-current or overheating is detected, or while the reverse current

prevention is operated.

A variable current limiting function is integrated, allowing the current limit value to be set, using an external resistor.

The voltage level which is fed to CE pin determines the status of XC8108. The logic level of CE pin is selectable between

either one of active high or active low.
