Startup Sequence of Power Supply (Voltage)
(1) When VM supply voltage
exceeds VMR voltage, charge
pump reset is cleared.
(2)
When charge pump voltage
exceeds the normal voltage
(Cp R) and after the
DCDC_READY time delayed,
3.3-V (5 V) DC/DC converter
reset is cleared, and 3.3-V
DCDC goes up.
(3) The DC/DC converter
operated with soft switching
Mode at initial charging up
through 90 % of the normal
voltage by current controlling.
After that, the converter is
operated with full-charging
Mode.
(4) When external signal
becomes High, 12-V DCDC
starts charging. (12-V DCDC
is switched from the soft
switching Mode to the full
Mode same as the 3.3-V
DCDC.)
