NCP303LSN17T1G Description

Short technical summary and product information.

The NCP303LSN17T1G from On Semiconductor is a 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 1.7V voltage threshold and an open drain output with an active low reset. The device operates over a wide voltage range of 0.8V to 10V and has a typical quiescent current of 0.5 uA. It is specified for operation across a temperature range of -40°C to +125°C.

 

This supervisor is housed in a compact SOT-23-5 Thin, TSOT-23-5 package, making it suitable for surface mount applications. The adjustable/selectable reset timeout feature provides design flexibility. The NCP303LSN17T1G is part of a series designed for ultra-low current consumption, prioritizing extended battery life in portable devices.

 

Typical applications include microprocessor reset controllers, low battery detection, power fail indicators, and battery backup detection. Its robust design and precise voltage monitoring make it a reliable component for power management in various electronic systems.
