NCP304A

NCP304A Voltage Detector Series The NCP304A is a second generation ultra−low current voltage detector. This device is specifically designed for use as a reset controller in portable microprocessor based systems where extended battery life is paramount. This device features a highly accurate undervoltage 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 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 1.0 mA Typical High Accuracy Undervoltage Threshold of 2.0% Wide Operating Voltage Range of 0.8 V to 10 V Complementary Output Active Low or Active High Reset Output This is a Pb−Free Device Typical Applications Microprocessor Reset Controller Low Battery Detection Power Fail Indicator Battery Backup Detection http://onsemi.com 4 1 SC−82AB SQ SUFFIX CASE 419C PIN CONNECTIONS AND MARKING DIAGRAM Vin 4 3 SUD M G G Reset Output NC 1 2 GND (Top View) SUD M G = Specific Device Code = Date Code = Pb−Free Package (Note: Microdot may be in either location) NCP304ALSQxxT1 Complementary Output Configuration 4 Input ORDERING INFORMATION See detailed ordering and shipping information in the ordering information sectio...
