Voltage Detector Series

The NCP304A is a second generation ultra−low current voltage detector. This device is specifically designed for use as a reset controller in portable microprocessor based systems where extended battery life is paramount.
This device features a highly accurate undervoltage detector with hysteresis which prevents erratic system reset operation as the comparator threshold is crossed.
The NCP304A consists of complementary output devices that are available with either an active high or active low reset output.
The NCP304A is 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.
