| 2 | IN2 | input | Input signal 2 (PWM logic input), recommended 0 to 5 V, absolute maximum -0.3 to 6 V. |
| 3 | IN1 | input | Input signal 1 (PWM logic input), recommended 0 to 5 V, absolute maximum -0.3 to 6 V. |
| 4 | VREF | power_in | Analog input (current-limit reference), recommended 0 to 5 V, absolute maximum -0.3 to 6 V. |
| 5 | VBB | power_in | Power supply, recommended 8 V to 40 V, absolute maximum 45 V. |
| 6 | OUT1 | output | H-bridge output 1, recommended 0 to 40 V, absolute maximum -2 to 40 V. |
| 7 | LSS | passive | Current-limit regulation (sense) output, recommended 0 to 0.3 V, absolute maximum -0.5 to 0.5 V. |
| 8 | OUT2 | output | H-bridge output 2, recommended 0 to 40 V, absolute maximum -2 to 40 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
