ACE ACE301X32XX+ High-precision low voltage detector Datasheet

ACE301
High-precision Low Voltage Detector
Description
ACE301 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.
ACE301 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.
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 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 CMOS pair.
+VDET, -VDET, VHYS can be calculated as follows:
-VDET =VREF*(1+Ra/(Rb+Rc))
+VDET =VREF*(1+(Ra+Rb)/Rb)=VREF *(1+(Ra+Rc)/Rb)
VHYS = +VDET-(-VDET)=VREF*(Ra+Rb+Rc)(1/Rb-1/(Rb+Rc))
