NCP345SNT1 Description

Short technical summary and product information.

The ON Semiconductor NCP345SNT1 is an Overvoltage Protection IC (OVP) designed to protect sensitive electronic components from overvoltage transients and power supply faults. It operates in conjunction with an external P-channel FET to quickly disconnect the input voltage supply from the load when an overvoltage condition is detected, preventing damage.

 

The device features a precise voltage reference, a comparator with hysteresis, control logic, and a MOSFET gate driver. It is built on a robust BiCMOS process and can withstand voltage transients up to 30V. The nominal overvoltage threshold is set at 6.85V, making it suitable for applications such as single-cell Li-Ion batteries, as well as 3/4-cell NiCD/NiMH applications.

 

Key electrical characteristics include an overvoltage turn-off time of less than 1.0 µs and compatibility with 1.8V logic levels for its CNTRL input. The NCP345SNT1 is available in a compact 5-TSOP (SOT-23-5 Thin) surface-mount package, supplied in tape and reel quantities of 3000 units.

 

Typical applications for this overvoltage protection IC include cellular phones, digital cameras, portable computers and PDAs, and portable CD players, where reliable protection against voltage fluctuations is critical.
