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 | VDD | power_in | Supply input. Operating range 2.8 V to 6.0 V (abs max 8 V, reverse -0.5 V). Typical IDD ~3.3 mA at 5 V, B=0. Bypass with a 1 nF/10 V ceramic near the pin per the application diagram. |+| 2 | OUTPUT | output | Push-pull analog Hall output, no pull-up required. VOUT = VDD/2 at B = 0 (VNULL). Slope for the D variant is 13.0 mV/Gs (linear over ±185 Gs); VOH ~4.9 V, VOL ~0.01-0.1 V, IO up to 1.5 mA source/sink, TSW ~150 µs. South-pole field near the top drives VOUT above VNULL, north-pole drives it below. Recommended 10 nF/10 V load cap to GND. |+| 3 | GND | power_in | Device ground. Must connect solidly to the supply return. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HUAXIN |+| Package | SOT-23 |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `HX6639ISO-DISO-A`+- `HX6639ISO-DISO-B`+- `HX6639ISO-DISO-C`+- `HX6639ISO-DISO-D`+- `HX6639ISO-DIUA-A`+- `HX6639ISO-DIUA-B`+- `HX6639ISO-DIUA-C`+- `HX6639ISO-DIUA-D`++## CAD (KiCad official)++- Symbol: `HX6639ISO-D`+- 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:** [HUAXIN datasheet](docs/hx6639iso-d-datasheet.pdf) (13 pp, sha256 `b848aed2dc79da33`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
