or longer before driving the motors.
Basically, the larger the Ccp 1 capacitance, the smaller the voltage fluctuation, though the initial charge
up time is longer.
The smaller the Ccp 1 capacitance, the shorter the initial charge-up time but the voltage fluctuation is
larger.
Depending on the combination of capacitors (especially with small capacitance), voltage may not be
sufficiently boosted.
When the voltage does not increase sufficiently, output DMOS R

raises the temperature.
Thus, use the capacitors under the capacitor combination conditions (Ccp 1
