How do I wire the A3291KUA-T?
It is a 3-wire open-drain device: connect supply, ground and output. The output needs an external pull-up resistor to the supply, commonly in the 1 kΩ to 10 kΩ range, so the line can go high when the device is not pulling it low. Confirm the pin order in the Allegro datasheet before wiring.
Can it run from 5 V or 12 V?
Yes. Its supply range is 3.5 V to 24 V, so both 5 V and 12 V rails are within range. When the pull-up resistor is tied to 5 V, the output can be read directly by a 5 V microcontroller input.
