Startup Time of Charge Pump
tONG: Time taken for capacitor Ccp2 (charging capacitor) to fill up Ccp1 (capacitor used to save charge) to VM +
VDD after a reset is released.
Until the voltage of Ccp1 reaches VM + VDD, the motor and the DCDC converter do not operate normally.
To prevent erroneous operations, the TB62205FG incorporates a protection circuit.
When the voltage of the charge pump is increased up to the specified level, the motor can operate
standalone. However, the initial charging of the DCDC converter starts at this timing. Thus, the DCDC
converter startup time should be included when the system startup time is set.
Basically, the larger the Ccp1 capacitance, the longer the initial charge-up time but the smaller the voltage
fluctuation.
The smaller the Ccp1 capacitance, the shorter the initial charge-up time but the larger the voltage
fluctuation.
Depending on the combination of capacitors (especially with small capacitance), voltage may not be
sufficiently boosted. Thus, use the capacitors under the capacitor combination conditions (Ccp1 = 0.22 F,
Ccp2 = 0.022 F) recommended by Toshiba.
