ACE ACE306X120XXX+ Low voltage detector with built-in delay circuit / ssd Datasheet

ACE306
Low Voltage Detector with Built-in Delay Circuit / SSD
Description
ACE306 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.
ACE306 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.

Function description
High precision low temperature co-efficiency reference voltage is applied to the negative input of a
comparator. Input voltage, divided by resistor array of Ra and Rb, is applied to the positive input of the
comparator. Output of the comparator passes a delay circuit and a series of buffer to drive the output
CMOS pair.
VDET =VREF*(1+Ra/Rb)
