NUS2045MN, NUS3045MN

Overvoltage Protection IC

with Integrated MOSFET

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.

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.
