ACE302
Low Voltage Detector with Built-in Delay Circuit
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.
