Figure 4. Operation Diagram
Step 1. The output voltage is equal to the supply voltage (VDD).
Step 2. At Point “A”, Vref >
= VDD×(Rb+Rc)/(Ra+Rb+Rc) is true, as a result, the output of comparator is reverse,
and output voltage becomes to Pull-up level. The voltage level of Point A means detector threshold
voltage, or (
VDET).
Step 3. At Point “B”, Vref >
= VDD×Rb/(Ra+Rb) is true, Output of the comparator is reverse, and output voltage is
equal to the GND after tpHL. The voltage level of Point B means released voltage, or (
+VDET).
The difference between released voltage and detector threshold voltage is the detector threshold hysteresis.
