This is an external voltage that can be applied to the output pin without deteriorating the quality of the
product or causing damage to the product.
Be sure to use the product within the rated value under any conditions where coils are inserted or power
is turned on or off. The output voltage that can be obtained during normal operation is within the output
saturation voltage range.

Note 5.
This parameter defines the voltage that can be applied when a PWM mode application circuit is
configured by applying an external voltage to the control pin. Usually, a capacitance of 0.01
