**Allegro MicroSystems LLC** · Linear Hall Sensors · SOT-23W

APS11700LLHALT-0PL from Allegro MicroSystems LLC, in a SOT-23W. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Positive supply input, 3.3 V to 24 V operating range (40 V absolute max). Requires a 0.1 µF bypass capacitor to GND placed close to the device; on-board reverse-battery and overvoltage protection. |
| 2 | VOUT | output | Open-drain NMOS switch output. Active-low ('L' polarity) - pulls to VOUT(SAT) (~100 mV @ 5 mA) when the magnetic field exceeds BOP; requires an external pull-up resistor (recommended ≤ 20 kΩ, e.g. 4.8 kΩ). Rated up to VOUT(OFF) = 24 V, IOUT = 40 mA max with internal short-circuit current limit of ~25 mA typ. |
| 3 | GND | power_in | Ground return for supply and output. Bypass capacitor CBYP (0.1 µF) connects between VCC and GND. |
