TMI8260SP from TMI, in a SOP-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 | IN2 | input | Reverse logic control input (IN2 high with IN1 low drives reverse, OUT2 to OUT1); the logic input voltage range is -0.3 V to 6 V and the logic input frequency is 0 to 50 kHz. |
| 2 | IN1 | input | Forward logic control input (IN1 high with IN2 low drives forward, OUT1 to OUT2); the logic input voltage range is -0.3 V to 6 V and the logic input frequency is 0 to 50 kHz. |
| 3 | GND | power_in | Device ground. |
| 4 | VCC | power_in | Power supply input with a recommended range of 3 V to 18 V; the absolute maximum rating is -0.3 V to 25 V. |
| 5 | OUT1 | output | Forward H-bridge output; the SOP8 continuous output current is rated 0 to 4.0 A. |
| 6 | OUT1 | output | Forward H-bridge output (shared with pin 5); the SOP8 continuous output current is rated 0 to 4.0 A. |
| 7 | OUT2 | output | Reverse H-bridge output; the SOP8 continuous output current is rated 0 to 4.0 A. |
| 8 | OUT2 | output | Reverse H-bridge output (shared with pin 7); the SOP8 continuous output current is rated 0 to 4.0 A. |
