HAL245UA

Hallwee · Linear Hall Sensors · TO-92S

HAL245UA 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 Positive supply pin with an operating range of 3.5 V to 24 V and an absolute maximum supply voltage of 28 V.
2 Gnd power_in Ground reference pin for the supply and the open-drain output.
3 Out output Open-drain output that goes low when the field reaches BOP and returns high below BRP; it requires an external pull-up resistor of 1K to 10K and the output current is limited to 10 mA maximum.

CAD (KiCad official)

  • Symbol: HAL245UA
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: hal245ua-etched.step / hal245ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hal245ua.step / hal245ua.glb are the bare package body.
