UCC27531DR from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No connection. |
| 2 | IN | input | Non-inverting input for driver control signal, accepts input voltage from -5 V to 25 V. |
| 3 | GND | power_in | Ground reference node (all signals are referenced to this node). |
| 4 | NC | unconnected | No connection. |
| 5 | NC | unconnected | No connection. |
| 6 | VDD | power_in | Bias supply voltage input with recommended operating range 10 V to 32 V. |
| 7 | OUT | output | Gate driver output with 2.5-A peak source current and 5-A peak sink current capability. |
| 8 | NC | unconnected | No connection. |
