Power management
The power management module monitors the different power supplies as well as it
generates the required internal supplies. The device can operate in the following
configurations:
4.15.1
Power management integration
Use the integration schemes provided below to ensure the proper device function,
according to the selected regulator configuration.
The internal regulators are supplied by VDD_HV_IO_MAIN supply and are used to generate
VDD_LV supply.
Place capacitances on the board as near as possible to the associated pins and limit the
serial inductance of the board to less than 5 nH.
It is recommended to use the internal regulators only to supply the device itself.

1. Standby regulator is automatically activated when the device enters standby mode.
2. For compatibility purpose with SPC584Cx/SPC58ECx, or for the optimization of the power dissipation, the operability of the
device with external ballast can be used. The external ballast option is available only on specific devices, contact the local
sales.
