Overvoltage Protection IC
with Integrated MOSFET
This device represents a new level of safety and integration by
combining the NCP304 overvoltage protection circuit (OVP) with a
?12 V P?Channel power MOSFET. It is specifically designed to
protect sensitive electronic circuitry from overvoltage transients and
power supply faults. During such hazardous events, the IC quickly
disconnects the input supply from the load, thus protecting the load
before any damage can occur.
