HAL2502SW

Hallwee · Linear Hall Sensors · DFN-4(1x1)

HAL2502SW from Hallwee, in a DFN-4(1x1). 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 OUT_S output CMOS push-pull output that goes low when the applied S-pole field exceeds Bop and returns high below Brp; absolute max output current is 5 mA.
2 VDD power_in Supply voltage pin, operating range 1.6 V to 5.5 V (absolute maximum 6 V, reverse 0.3 V), with a 1 uF bypass capacitor recommended.
3 OUT_N output CMOS push-pull output that goes low when the applied N-pole field exceeds Bop and returns high below Brp; absolute max output current is 5 mA.
4 GND power_in Ground pin.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

  • Symbol: HAL2502SW
  • Footprint: Package_DFN_QFN:UDFN-4-1EP_1x1mm_P0.65mm_EP0.48x0.48mm
  • 3D model: DFN-4(1x1) (KiCad packages3D, STEP)
  • 3D model files: hal2502sw-etched.step / hal2502sw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hal2502sw.step / hal2502sw.glb are the bare package body.

Provenance

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