Charge Pump Rise Time
tONG:
Delay time taken for capacitor Ccp 2 (charging capacitor) to fill up Ccp 1 (storing capacitor) to VM + VDD
after STANDBY is released.
The internal IC cannot drive the gates correctly until the voltage of Ccp 1 reaches VM + VDD. Be sure to
wait for tONG 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 RON turns lower than the normal, and it
raises the temperature.
Thus, use the capacitors under the capacitor combination conditions (Ccp 1 = 0.22 F, Ccp 2 = 0.022 F)
recommended by Toshiba.
