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 voltage input, 2.5 V to 6 V operating range (7 V absolute max). Typical supply current 2.6 mA. Reverse voltage protection not included; a 100 Ω series resistor is recommended for reverse protection. |+| 2 | Output | output | Open-drain digital output. Pulls low (VDSON <= 400 mV at 10 mA) when magnetic field exceeds operate point (|B| > BOP, typ 30 Gauss); high-impedance (leakage <= 10 uA) when released. Requires external pull-up (typ 10 kOhm). Max sink current 25 mA; output voltage max 6 V. |+| 3 | GND | power_in | Ground reference pin for the device. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MST Magnesensor Tech MST |+| Package | SOT-23-3L |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `MH253ESOESO`+- `MH253ESOESQ`+- `MH253ESOEUA`+- `MH253ESOKUA`++## CAD (KiCad official)++- Symbol: `MH253ESO`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MST Magnesensor Tech MST datasheet](docs/mh253eso-datasheet.pdf) (5 pp, sha256 `9d3b31b816690eaa`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
