7.3.8 RESET Function

The RESET function allows the comparator to work in transparent mode or latching mode. Figure 7-4 shows the two modes of the RESET function. When the RESET pin is left open or connected to GND the comparator functions in a transparent mode. In transparent mode comparator output (CMPOUT ) responds as a normal comparator. When the RESET pin is connected to the supply voltage, the pin operates in latching mode. In the latching mode when the comparator is triggered by the comparator input going higher than 0.6 V, the output of the comparator stays high irrespective of comparator input after. To release the comparator from the latching mode, the RESET pin must be pulled to GND or released to open. The RESET pin can take a voltage range from 0 V to the power-supply voltage.
