DESCRIPTION

A4804 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at VDD = 3.0V). It can work at very low voltage, which makes it perfect for system reset.

A4804 is composed of high precision voltage reference, comparator, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming.

N-channel open-drain is available.

A4804 is available in SOT-23 package.
