NCP302LSN43T1

Voltage Detector Series with Programmable Delay

ON Semiconductor 

NCP302, NCP303

Voltage Detector Series

with Programmable Delay

The NCP302 and NCP303 series are second generation ultra−low

current voltage detectors that contain a programmable time delay

generator. These devices are specifically designed for use as reset

controllers in portable microprocessor based systems where extended

battery life is paramount.

Each series features a highly accurate undervoltage detector with

hysteresis and an externally programmable time delay generator. This

combination of features prevents erratic system reset operation.

The NCP302 series consists of complementary output devices that

are available with either an active high or active low reset. The

NCP303 series has an open drain N−Channel output with an active low

reset output.

Features

• Quiescent Current of 0.5 mA Typical

• High Accuracy Undervoltage Threshold of 2.0%

• Externally Programmable Time Delay Generator

• Wide Operating Voltage Range of 0.8 V to 10 V

• Complementary or Open Drain Output

• Active Low or Active High Reset

• Specified Over the −40°C to +125°C Temperature Range

(Except for Voltage Options from 0.9 to 1.1 V)

• Pb−Free Packages are Available

Typical Applications

• Microprocessor Reset Controller

• Low Battery Detection

• Power Fail Indicator

• Battery Backup Detection
