DRV5055Z3QDBZR from Texas Instruments, in a SOT-23. 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 | VCC | power_in | Power supply input for the 3.3 V or 5 V supply; TI recommends a ceramic capacitor to ground of at least 0.01 µF on this pin. |
| 2 | OUT | output | Analog ratiometric output, centered at VCC / 2 with no magnetic field, with continuous output current limited to ±1 mA. |
| 3 | GND | power_in | Ground reference for the device. |
