**Texas Instruments** · Linear Hall Sensors · SOT-23

DRV5056A3QDBZR 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 | Supply voltage input in the range of 3.3V or 5V ±10%, with TI recommending connection to at least a 0.1µF ceramic capacitor to ground for power supply decoupling. |
| 2 | OUT | output | Analog output voltage proportional to applied magnetic flux density, with quiescent voltage of 0.6V (typical) at B=0mT and sensitivity of 50mV/mT (typical) at VCC=5V for the DRV5056A3 variant. |
| 3 | GND | power_in | Ground reference providing the electronic return path for the power supply and output signals. |
