Energy harvesting and LPD: can EH still be active when the ST25 pin is put in LPD mode (the goal is to reduce the whole consumption in EH mode) ?

​Hello,

Yes, definitely. EH is completely independent of LPD, so you can have EH power when device in low power mode as well as when device has no VCC.

Best regards.

Hi,

I need to power the STM32L4 with the energy output from the EH pin. May I ask why my LD3 power point is lit by EH pin, but the MCU does not work normally?
