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. |
