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 ...
