NCP303LSN44T1G Description

Short technical summary and product information.

The ON Semiconductor NCP303LSN44T1G is a second-generation, ultra-low current voltage detector featuring 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 offers a highly accurate undervoltage detector with hysteresis and an externally programmable time delay, preventing erratic system resets. It has a fixed 4.4V threshold and an active low reset output with an open drain configuration. The operating voltage range is from 0.8V to 10V, with a quiescent current of 0.5 μA typical.

 

The NCP303LSN44T1G is specified over a wide temperature range of -40°C to +125°C. It comes in a compact 5-TSOP package, suitable for surface mount applications. This component is Pb-free and RoHS compliant.

 

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