Overvoltage Protection IC
with Integrated MOSFET
combining the NCP346 overvoltage protection circuit (OVP) with a
30 V P−channel power MOSFET. This IC 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.
AC−DC adapter or a car accessory charger to power a portable product
or recharge its internal batteries. It has a nominal overvoltage
threshold of 5.5 V which makes it ideal for single cell Li−Ion as well
as 3/4 cell NiCD/NiMH applications.
