NCP345  
Overvoltage Protection IC  
The NCP345 overvoltage protection circuit (OVP) protects  
sensitive electronic circuitry from overvoltage transients and power  
supply faults when used in conjunction with an external P−channel  
FET. The device is designed to sense an overvoltage condition and  
quickly disconnect the input voltage supply from the load before any  
damage can occur. The OVP consists of a precise voltage reference, a  
comparator with hysteresis, control logic, and a MOSFET gate driver.  
The OVP is designed on a robust BiCMOS process and is intended to  
withstand voltage transients up to 30 V.  
The device is optimized for applications that have an external  
AC/DC adapter or car accessory charger to power the product and/or  
recharge the internal batteries. The nominal overvoltage threshold is  
6.85 V so it is suitable for single cell Li−Ion applications as well as 3/4  
cell NiCD/NiMH applications.
