XC8108 Series

85mΩ High Function Power Switch with Current Limit Adjustable Pin

The XC8108 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.

A variable current limiting function is integrated, allowing the current limit value to be set within the range of 0.9A to 2.4A (TYP.) using an external resistor. The IC can be put in the stand-by state using the level of the voltage applied to the CE pin. CE pin logic is available in two types, active high or active low.
