PINTYPEDESCRIPTION
NO.NAME
1VDD1High-side powerHigh-side power supply.(1)
2INAnalog inputAnalog input pin to the window comparator.
3REFAnalog inputReference pin that defines the trip threshold. The voltage on this pin also affects the hysteresis of comparator Cmp0, as explained in the Reference Input section. This pin is internally connected to a 100-μA current source. Connect a resistor from REF to GND1 to define the trip threshold, and a capacitor from REF to GND1 to filter the reference voltage. For best transient noise immunity, place the capacitor as closely to the pin as possible. This pin can also be driven by an external voltage source.
4GND1High-side groundHigh-side ground.
5GND2Low-side groundLow-side ground.
6OUTDigital outputOpen-drain output of the window comparator. Connect to an external pullup resistor.
7LATCHDigital inputDigital input to select latch mode (high) or transparent mode (low) of the open-drain output. Do not leave the input pin unconnected (floating). Connect to GND2 when not used.
8VDD2Low-side powerLow-side power supply.(1)
