DRV5055A1QDBZR from Texas Instruments, in a SOT-23. 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 | VCC | power_in | Power supply input, 3 V to 3.63 V or 4.5 V to 5.5 V. TI recommends connecting this pin to a ceramic decoupling capacitor of at least 0.01 µF to GND. |
| 2 | OUT | output | Analog output voltage. Quiescent voltage is VCC/2 (B = 0 mT); voltage swings proportionally with applied magnetic flux density (sensitivity from 12.5 mV/mT to 100 mV/mT depending on variant). Can drive ±1 mA. |
| 3 | GND | power_in | Ground reference for the device. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 583 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.
