NCV303LSN42T1G Description

Short technical summary and product information.

The NCV303LSN42T1G from ON Semiconductor is a second-generation, ultra-low current voltage detector designed for microprocessor reset control in portable systems. It features a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator to prevent erratic system resets.

 

Key electrical specifications include a nominal voltage of 4.2V, an operating voltage range from 0.8V to 10V, and a typical quiescent current of 0.5 µA. The device offers an active low reset output and an open drain or open collector output configuration. The undervoltage threshold accuracy is 2.0%.

 

This voltage detector is specified for operation over a temperature range of -40°C to +125°C. It is supplied in a 5-TSOP / SOT-23-5 package, suitable for surface mount applications. The NCV303LSN42T1G is designed for applications such as microprocessor reset controllers, low battery detection, power fail indicators, and battery backup detection.
