Overvoltage Protection IC

with Integrated MOSFET

These devices represent a new level of safety and integration by

combining the NCP345 overvoltage protection circuit (OVP) with a

20 V P−channel power MOSFET (NUS2045MN) or with a 30 V

P−channel power MOSFET (NUS3045MN). They are 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.

The OVP ICs are optimized for applications using an external

AC−DC adapter or a car accessory charger to power a portable product

or recharge its internal batteries. They have a nominal overvoltage

threshold of 6.85 V which makes them ideal for single cell Li−Ion as

well as 3/4 cell NiCD/NiMH applications.
