Overvoltage Protection IC

The NCP346 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 thresholds are

4.45 and 5.5 V and can be adjusted upward with a resistor divider
