8 / 19 page ACE301 Technology High-precision Low Voltage Detector VER 1.3 8 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)) |
