NCP345SNT1G Description

Short technical summary and product information.

The NCP345SNT1G from ON Semiconductor is an Overvoltage Protection (OVP) Integrated Circuit designed to protect sensitive electronic components from overvoltage transients and power supply faults. It functions in conjunction with an external P-channel FET to quickly disconnect the input voltage supply from the load before damage can occur.

Key electrical characteristics include a precise nominal overvoltage threshold of 6.85 V, making it suitable for applications like single-cell Li-Ion batteries. It also offers undervoltage lockout protection and a fast overvoltage turn-off time of less than 1.0 µs. The CNTRL input is compatible with 1.8 V logic levels.

This device is designed on a robust BiCMOS process and can withstand voltage transients up to 30 V. It is optimized for applications using external AC/DC adapters or car accessory chargers. The NCP345SNT1G is housed in a compact SOT-23-5 Thin package, suitable for surface mount applications.

Typical applications include cellular phones, digital cameras, portable computers and PDAs, and other portable consumer electronics.
