A4809 - LOW VOLTAGE DETECTOR

Datasheet Summary

Features

  • A4809 is a series of high precision voltage detector with ultra-low current consumption (4.5uA typ. at VIN=3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system reset. A4809 is composed of high precision voltage reference, comparator, delay circuit, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming. Two type of output, CMOS and N-channel open-drain are available.
