NCV303LSN45T1G Description

Short technical summary and product information.

The NCV303LSN45T1G from ON Semiconductor is a second-generation ultra-low current voltage detector. It is designed for use as reset controllers in portable microprocessor-based systems where extended battery life is crucial.

 

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 with a quiescent current of 0.5 µA typical. The undervoltage threshold accuracy is 2.0%.

 

The NCP303 series, including the NCV303LSN45T1G, has an open drain N-Channel output with an active low reset. It is specified over a temperature range of -40°C to +125°C. The device is available in a 5-TSOP package and is suitable for surface mount.

 

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, being AEC-Q100 qualified and PPAP capable.
