NCP304, NCP305

Voltage Detector Series

The NCP304 and NCP305 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 NCP304 series consists of complementary output devices that

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

NCP305 series has an open drain N−Channel output with an active low

reset output.

The NCP304 and NCP305 device series are available in the

SC−82AB package with standard undervoltage thresholds. Additional

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

be manufactured.
