Product Description


85mΩ Power Switch with Fixed Current Limit

The XD8107 is a P-channel MOSFET power switch IC which combines low ON resistance and a high accuracy current limit circuit. Designed for applications where precision current limiting is required the XC8107 is an ideal choice for USB ports protection.

Current limit, reverse current prevention (prevents reverse current from VOUT to VIN), soft start, thermal shutdown and 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 a 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. CE pin logic is available in two types, active high or active low.

Available in SOT-25 & USP-6C packages.
