Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN1 | input | Logic input for bridge 1 (OUT1/OUT2); high level requires VIN ≥ 2 V, low level VIN ≤ 0.8 V, with 300 mV hysteresis and an internal pull-down of 60-100 kΩ. |
| 2 | IN2 | input | Logic input for bridge 1 (OUT1/OUT2); high level requires VIN ≥ 2 V, low level VIN ≤ 0.8 V, with 300 mV hysteresis and an internal pull-down of 60-100 kΩ. |
| 3 | VBB | power_in | Motor/bridge supply input; operating supply range is 4 V to 18 V, with an absolute maximum of 28 V. |
| 4 | IN3 | input | Logic input for bridge 2 (OUT3/OUT4); high level requires VIN ≥ 2 V, low level VIN ≤ 0.8 V, with 300 mV hysteresis and an internal pull-down of 60-100 kΩ. |
| 5 | IN4 | input | Logic input for bridge 2 (OUT3/OUT4); high level requires VIN ≥ 2 V, low level VIN ≤ 0.8 V, with 300 mV hysteresis and an internal pull-down of 60-100 kΩ. |
