NCP303LSN46T1G Description

Short technical summary and product information.

The NCP303LSN46T1G 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 4.6V voltage threshold, an open drain output, and an active low reset. The device operates over a wide voltage range of 0.8V to 10V and maintains a low quiescent current of 0.5 µA typical. The operating temperature range is specified from -40°C to +125°C.

 

This voltage detector is housed in a 5-TSOP package, suitable for surface mount applications. Its design is optimized for applications requiring reliable power-on reset and low battery detection, contributing to extended battery life in portable devices.

 

Typical applications include microprocessor reset controllers, low battery detection, power fail indicators, and battery backup detection.
