TMAG5111A4AQDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 at 2.5V to 38V; connect a ceramic capacitor of at least 0.01µF between VCC and GND. |
| 2 | GND | power_in | Reference ground for the device. |
| 3 | NC | unconnected | No internal connection; the datasheet recommends connecting this pin to the ground pin. |
| 4 | OUT1 | output | Open-drain output 1, which is the speed output on the TMAG5111-Q1; sink current is limited to 10mA maximum. |
| 5 | OUT2 | output | Open-drain output 2, which is the direction output on the TMAG5111-Q1; sink current is limited to 10mA maximum. |
