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.
Features
High-precision detection Voltage:±3%

Function description
High precision low temperature coefficiency reference voltage is applied to the negative input of a
comparator. Input voltage, divided by resistor array of Ra Rb and Rc, is applied to the positive input of the
comparator. Output of the comparator controls a pair of NMOS and PMOS switches, generating the
hysteresis. Output of the comparator passes a series of buffer to drive the output NMOS.
