Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin; all grounding wires must run on the solder mask of the PCB and be externally terminated at a single point. |
| 2 | IN2 | input | Logic input pin 2; VIN(H) is 2.0 V (min) to 5.5 V (max) and VIN(L) is 0 V (min) to 0.8 V (max). |
| 3 | IN1 | input | Logic input pin 1; VIN(H) is 2.0 V (min) to 5.5 V (max) and VIN(L) is 0 V (min) to 0.8 V (max). |
| 4 | VREF | power_in | Motor output current setting pin; the applied voltage range is 0 V to 4.0 V, with 2.0 V to 4.0 V specified for constant current drive. |
| 5 | VM | power_in | Motor power supply; the operating range is 4.5 V (min) to 44 V (max), and it is rated at 50 V (non-active, standby mode). |
| 6 | OUT1 | output | Motor output pin 1; the OUT pin voltage range is 4.5 V (min) to 50 V (max), and the motor output current is rated at 3.5 A absolute maximum. |
| 7 | RS | input | Motor output current sense pin; it connects to the current-sensing resistor RRS, and must be connected to GND if constant current control is disabled. |
| 8 | OUT2 | output | Motor output pin 2; the OUT pin voltage range is 4.5 V (min) to 50 V (max), and the motor output current is rated at 3.5 A absolute maximum. |
