Pulled low (Vsat ~0.05 V typ at 1 mA) when |B| > BOP; released high when |B| < BRP. Max Iout 5.0 mA; leakage <0.01 uA typ. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GoChip Elec Tech Shanghai |+| Package | SOT-23-3L |+| Category | Sensor |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `GH1248ESW`+- 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:** [GoChip Elec Tech Shanghai datasheet](docs/gh1248esw-datasheet.pdf) (9 pp, sha256 `6a2aca797ed7f856`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
