NCP300

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. Features Quiescent Current of 0.5 mA Typical High Accuracy Undervoltage Threshold of 2.0% Wi...
