PWM Speed Control
It is easy to change rotation speed of the motor by switching output transistor. The
on-duty of switching depends on the input signal to PWM terminal. The rotation speed of
the motor is proportional to the duty ratio of the input signal to PWM terminal.
The PWM terminal is internally pulled high. When PWM terminal is open, it is equal to
PWM terminal has input hysteresis. It is
±
600mV (Typ.)
