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
