Operating Description
PWM control function
Speed can be controlled by inputting the high-level or low-level PWM signal to the pin PWM.
When PWM control is provided, normal operation and short brake operation are repeated.
To prevent penetrating current, dead time (t2 and t4) is provided in the IC.
Note: Be sure to set the PWM pin to high if the PWM control function is not used.
