BQ40Z80: Best way to power MCU

Hi Saero,

I do not believe that the STM32 is a TI product, meaning I cannot confidently give a recommendation on how to power this device. I believe this question would be better suited for their team.

Hello Anthony,
Let me rephrase then. What's the best way to power Ti MCU while using BQ40Z80?
Thank you!

Hi Saero,

I believe the bq40z80 EVM implements a TI MCU for reference, the bq40z80EVM User's Guide has the schematic below:

Hey,

I do have few of the EVMs. I wanted to understand how we can utilise MCU and power it when pack is removable. I would like to disable MCU once bq40z80 is at sleep. Enable MCU with a push button latch power until it's disabled. 

Any suggestions? 

Hi Saero,

I believe this would be a question better suited to be posted on the MSP E2E since they would have a better idea of how to go about this situation.

Anthony
