Connect a 0.1μF bypass ceramic capacitor to GND. A 1 VM bulk capacitor with at least 22μF capacitance on VM to GND is needed and helpful to stabilize VM voltage during motor operation. 2 OUT1 Motor Driver output 1 3 OUT2 Motor Driver output 2 4 GND Ground pin 5 IN2 PWM input2 6 IN1 PWM input1 Chip Enable Input Pin. When this pin is in logic low, the device enters 7 EN low-power sleep mode. The device operates normally when this pin is logic high. The pin has an internal pull-down resistor to GND. 8 VCC Power Supply for Logic Input.
