Product Description

The GLF2204 is an integrated Over voltage protection (OVP) power switch. There are external and internal OVP thresholds. The device provides more protection features which are under voltage lockout, programmable current and thermal shutdown.


The external OVP threshold is adjusted by an external resistor divider from 4.5 V to 9 V. The device has an internal fixed OVP threshold voltage when the OVLO pin voltage is lower than an external OVP set threshold voltage (VOVP_TH). When an input voltage of VIN exceeds the over voltage threshold, the GLF2204 will be turned off immediately to isolate the system from the input source.
