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.
