XC8109AC10ER-G

The XC8109 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, using an external resistor. The voltage level which is fed to CE pin determines the status of XC8109. The logic level of CE pin is selectable between either one of active high or active low.
