Operating range 3.3 V to 24 V. Should be bypassed with a 0.1 uF ceramic capacitor to GND close to the device. |+| 2 | VOUT | output | Open-drain Hall switch output. Requires an external pull-up resistor to VCC or another rail. Pulls low when the magnetic field crosses the operate threshold and releases at the release threshold. |+| 3 | GND | power_in | Ground reference. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Allegro MicroSystems LLC |+| Package | SOT-23W |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `A1220LLHLT-TLLHLT-T`+- `A1220LLHLT-TLUA-T`++## CAD (KiCad official)++- Symbol: `A1220LLHLT-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/a1220llhlt-t-datasheet.pdf) (16 pp, sha256 `23fb399359de64eb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
