Product Description

The GLF2201 is an integrated over voltage protection (OVP) power switch. It has under voltage lockout, output short circuit and over temperature protection functions. The device has an internal fixed OVP threshold, and a programmable OVP threshold that can be programmed by an external resistor divider on OVLO pin. When the input voltage is higher than the OVP threshold, the internal main FET is turned off immediately to isolate the downstream loads from input power supply. The GLF2201 restore on after the input voltage lower than the OVP threshold. The device has an internal 8 ms recovery time before the device fully restore on.


The GLF2201 is available in the 2 mm x 2mm DFN package with 6 leads.
