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 Pchannel power MOSFET (NUS2045MN) or with a 30 V
Pchannel 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
ACDC 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 LiIon as
well as 3/4 cell NiCD/NiMH applications.
