NCP304数据手册集成电路（IC）的监控器规格书PDF

描述 Description

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 under voltage 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 withstandard under voltage thresholds. Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
