85mΩ High Function Power Switch

The XC8107 series is a P-channel MOSFET power switch IC with a low ON resistance.

A current limit, reverse current prevention (prevents reverse current from VOUT to VIN), soft start, thermal shutdown, and an under voltage lockout (UVLO) are 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. The IC can be put in the stand-by state using the level of the voltage applied to the CE pin. High active or Low active can be selected for the CE pin input logic.
