GH1248ESW

GoChip Elec Tech Shanghai · Hall Sensor · SOT-23-3L

GH1248ESW from GoChip Elec Tech Shanghai, in a SOT-23-3L. 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 Positive supply input. Operating range 1.8 V to 5.5 V; absolute max 7.0 V. Bypass with ~10 nF to GND close to the pin (per Figure 5).
3 GND power_in Ground reference pin (SOT-23-3L pin 3; SIP-3L pin 2; DFN1616-3 pin 3).
2 OUTPUT output Digital latched output driven by internal open-drain NMOS with built-in pull-up resistor to VDD. Pulled low (Vsat ~0.05 V typ at 1 mA) when

CAD (KiCad official)

  • Symbol: GH1248ESW
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: gh1248esw-etched.step / gh1248esw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gh1248esw.step / gh1248esw.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
gh1248esw.step 59 KB You want the bare part, or you mark your own boards.
gh1248esw-etched.step 1.7 MB You want the part with GH1248ESW already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 415 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: GoChip Elec Tech Shanghai datasheet (9 pp, sha256 6a2aca797ed7f856, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
