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 |B| > B_OP and releases (Hi-Z) when |B| < B_RP. Maximum 30 mA sink, r_DS(on) ~22 ohm at 3.3 V/10 mA, overcurrent protection typ 30 mA. |+| 3 | GND | power_in | Ground pin.
