NCP300, NCP301

Voltage Detector Series

The NCP300 and NCP301 series are second generation ultra−low

current voltage detectors. 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 which prevents erratic system reset operation as the

comparator threshold is crossed.

The NCP300 series consists of complementary output devices that

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

NCP301 series has an open drain N−Channel output with either an

active high or active low reset output.

The NCP300 and NCP301 device series are available in the

Thin TSOP−5 package with standard undervoltage thresholds.

Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps

can be manufactured.
