ACE303 High-precision Low Voltage Detector Description ACE303 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.
ACE303 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.
One type of output, N-channel open-drain is available.
