NCP304A中文资料Voltage Detector with Reverse Pin Out数据手册ONSEMI规格书

描述 Description

The NCP304A is a second generation ultra-low current voltage detector. The device is specifically designed for use as a reset controller in portable microprocessor based systems where extended battery life is paramount. The device features a highly accurate under voltage 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 under voltage thresholds. Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
