NAME

VDD1

High-side power

High-side power supply.(1)

Analog input

Analog input pin to the window comparator.

REF

Analog input

Reference 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.

GND1

High-side ground

High-side analog ground.

GND2

Low-side ground

Low-side analog ground.

OUT

Digital output

Open-drain output of the window comparator. Connect to an external pullup resistor.

LATCH

Digital input

Digital 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.

VDD2

Low-side power

Low-side power supply.(1)
