Digital omnipolar Hall-effect switch with a chopper-stabilized front end, in a SOT-23 package. The open-drain output pulls low when the magnetic flux density of either polarity exceeds the B_OP threshold and releases to high-impedance below B_RP. It runs from 2.5 to 38 V with reverse-supply protection to -22 V, sinks 30 mA, and has built-in overcurrent protection. Used for proximity, position, tamper, and rotation sensing next to a magnet.

Pinout

Pin	Name	Type	Function
1	VCC	power_in	2.5 to 38 V power supply. Bypass this pin to GND with a 0.01 uF (minimum) ceramic capacitor rated for VCC. Typical operating supply current is 2.7 mA at 25 degC. Reverse-supply protection down to -22 V.
2	OUT	output	Hall sensor open-drain output. Requires an external pullup resistor. Output goes low when
3	GND	power_in	Ground pin. Device reference for VCC and OUT.
