Pinout
8| Pin | Name | Functions | Notes |
|---|---|---|---|
| 1 | GND | POWERGND | Logic ground. Connect to board ground. |
| 2 | IN2 | GPIO | Logic inputs. Controls the H-bridge output. Has internal pulldowns. |
| 3 | IN1 | GPIO | Logic inputs. Controls the H-bridge output. Has internal pulldowns. |
| 4 | VREF | ADC | Analog input. Apply a voltage between 0.3 to 5 V. |
| 5 | VM | POWER | 6.5-V to 45-V power supply. Connect a 0.1-µF bypass capacitor to ground, as well as sufficient bulk capacitance, rated for the VM voltage. |
| 6 | OUT2 | PWM | H-bridge output. Connect directly to the motor or other inductive load. |
| 7 | ISEN | ADC | High-current ground path. If using current regulation, connect ISEN to a resistor (low-value, high-power-rating) to ground. If not using current regulation, connect ISEN directly to ground. |
| 8 | OUT1 | PWM | H-bridge output. Connect directly to the motor or other inductive load. |
