FAQ: STM32MP1 what alternative to STPMIC for application supply

   Do we have to use the STPMIC with the STM32MP1?

No, as an alternative it is possible to use discrete voltage regulators instead. Both solutions have some pros and cons.
STPMIC significantly simplifies hardware design, offers advanced features such as short-circuit detection and it features USB power.
Note also that the OpenSTlinuxBSP software is ready to controls low-power states with STPMIC compagnon chip.


The application note AN5256 STM32MP15x Lines discrete power supply hardware integration.pdf provides system level information for power distribution for application that does not chose to embeds STPMIC1.
