NCP302LSN43T1G Description

Short technical summary and product information.

The ON Semiconductor NCP302LSN43T1G is a second-generation, ultra-low current voltage detector with a programmable time delay generator. It is designed for use as a reset controller in portable microprocessor-based systems where extended battery life is critical.

 

This device features a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator, preventing erratic system reset operations. It operates over a wide voltage range of 0.8 V to 10 V and has a quiescent current of 0.5 µA typical. The undervoltage threshold accuracy is 2.0%.

 

The NCP302LSN43T1G has an active low reset output and is available in a 5-TSOP package, specifically SOT-23-5 Thin, suitable for surface mount applications. It is specified over a temperature range of -40°C to +125°C.

 

Typical applications include microprocessor reset controllers, low battery detection, power fail indicators, and battery backup detection. The NCV prefix indicates suitability for automotive and other applications requiring unique site and control change requirements, with AEC-Q100 qualification and PPAP capability.
