Pin Functions
| PIN | TYPE | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | NO. | |||
| GND | 1 | PWR | Logic ground | Connect to board ground. |
| IN1 | 3 | I | Logic inputs | Controls the H-bridge output. Has internal pulldowns. (See Table 1.) |
| IN2 | 2 | |||
| ISEN | 7 | PWR | 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. |
| nFAULT | 4 | OD | Fault status (open-drain) | Low-level indicates UVLO, TSD, or OCP fault. Connect to a pullup resistor. |
| OUT1 | 6 | O | H-bridge outputs | Connect directly to the motor, or other inductive load. |
| OUT2 | 8 | |||
| VM | 5 | PWR | 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. |
| PAD | — | — | Thermal pad | Connect to board ground. For good thermal dissipation, use large ground planes on multiple layers, and multiple nearby vias connecting those planes. |
