Application Example 2
[Fixed Speed + Soft Start]
With this circuit, the motor speed remains constant even if there are fluctuations in the supply voltage or static voltage.

Input a fixed-duty signal to the CTL pin signal input as an input signal for which soft start is enabled at startup.
Alternatively, apply a constant voltage to the C pin. (In this case, the CTL pin must be left open.)
