Hello everyone
In my application using an STM32H7, I noticed that the VBAT pin, with VDD off, draws 1.9 mA. This is excessive current draw.
I'm using a CR2032 battery in series with a 100R battery connected to the microcontroller's VBAT pin.
What could be the cause?
Is there any way to understand why it's drawing so much current?
NB: The datasheet states that the RTC draws 225 nA at 1.2 V, including the LSE's power consumption.
Thanks
