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 | OUT | output | Open-collector Hall latch output. Sinks up to ~20 mA (VOL <= 0.7 V at 12 mA); latches LOW when magnetic flux exceeds BOP (~5 mT) and latches HIGH when flux drops below BRP (~-5 mT). Requires an external pull-up resistor (e.g. 10 kOhm) to VCC. |+| 2 | VCC | power_in | Supply voltage input, 2.5 V to 20 V. Typical supply current ~6 mA at 16 V, ~5.5 mA at 3.6 V; absolute max ICC 10 mA. Built-in protection diode is present on this pin. |+| 3 | GND | power_in | Ground reference for the device. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | SOT-23 |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `SK1816G-AE3-RAE3-R`+- `SK1816G-AE3-RG03-B`+- `SK1816G-AE3-RG03-K`++## CAD (KiCad official)++- Symbol: `SK1816G-AE3-R`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UTC Unisonic Tech datasheet](docs/sk1816g-ae3-r-datasheet.pdf) (8 pp, sha256 `45430608d678b140`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
