Ultra Low Rds(on) High Current Capability OVP


WP3981 can disconnect the systems from its output pin(OUT) in case wrong input operating conditions are detected. The internal overvoltage thresholds (OVLO) is 13.75V. WP3981 has internal Thermal-Shutdown Protection and Input Voltage detection.

The device is packaged in advanced full-Green compliant DFN. The OVP switch with over voltage protection feature a low 8mΩ(TYP) on-resistance(RON) internal FET and protect low-voltage systems against voltage faults up to 28 VDC.
