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 | Supply voltage input. Operating range 3.0 V to 24 V. A bypass capacitor (typ. 0.1 µF) from VCC to GND is recommended for noise immunity. |+| 2 | GND | power_in | Ground return for the device. |+| 3 | VOUT | output | Open-drain digital Hall switch output. Sinks up to 25 mA when the magnetic field exceeds the operate point (BOP); high-impedance (requires external pull-up) when the field falls below the release point (BRP). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Allegro MicroSystems LLC |+| Package | SOT-23W |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `A1120LLHLT-TLLHLT-T`+- `A1120LLHLT-TLUA-T`++## CAD (KiCad official)++- Symbol: `A1120LLHLT-T`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23W (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Allegro MicroSystems LLC datasheet](docs/a1120llhlt-t-datasheet.pdf) (18 pp, sha256 `2e2d51c564dee4c6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
