Low Voltage Detector with Built-in Delay Circuit

VER 1.2

Description

ACE302 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at

Vdd=3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system

reset.

ACE302 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.

ACE302 is available in SOT-23-3 which is Pb free.
