Figure AS3630 – 19:
Supercap Pre-charging
• Transition3 between pre-charge -> charge: Once the
voltage on VSUPERCAP is close to VVIN and mode_setting
= “Supercap charge”, the DCDC1 converter is started and
the current source ICHARGE between VDCDC and
VSUPERCAP is used to finally charge VSUPERCAP to VVIN
3. To avoid a current peak at VIN if the VSUPERCAP is connected to VIN, but its voltage is still below VIN
