Voltage Detector Series NCP304, NCP305 The NCP304 and NCP305 series are second generation ultralow 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 www.onsemi.com 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 4 NCP305 series has an open drain NChannel output with an active low 1 reset output. SC82AB The NCP304 and NCP305 device series are available in the SQ SUFFIX SC82AB package with standard undervoltage thresholds. Additional CASE 419C thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
