HAL49EUA

Hallwee · Linear Hall Sensors · TO-92S

HAL49EUA from Hallwee, in a TO-92S. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Power supply pin, operating range 3 V to 6.5 V (5 V typical), absolute maximum 8 V.
2 GND power_in Ground pin.
3 OUT output Linear analog output of 2.5 V typical at zero field (B=0 Gs, VDD=5 V), output resistance 40 ohm typical and 100 ohm max, output current limit 20 mA.

CAD (KiCad official)

  • Symbol: HAL49EUA
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: hal49eua-etched.step / hal49eua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hal49eua.step / hal49eua.glb are the bare package body.
