PRODUCT DESCRIPTION
The GLF2201 is an integrated over voltage protection (OVP) power switch. It also features under voltage lockout, output short circuit and over temperature protection functions. The device has an internal fixed OVP threshold as well as a programmable one by the external resistor divider on an OVLO pin. When a higher voltage than the OVP threshold is applied, the internal main FET is turned off immediately to isolate low voltage powered systems from the input source. The GLF2201 turns back on after the input voltage becomes normal below the OVP threshold. The device has an internal 8 ms recovery time before the device resumes after fault conditions. The GLF2201 is available in the 2 mm x 2mm DFN package with 6 leads.
