The NCP/NCV300 and NCP/NCV301 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 NCP/NCV300 series consists of complementary output devices thatare 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 NCP/NCV300 and NCP/NCV301 device series are available in the Thin SOT23-5 package with standard under voltage thresholds. Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
