Dear Sir/Ms.

What is the purpose of this button in the picture? How to boot? BQ76200 is packaged in the battery pack, how to use this function? Can I remove this button?

Best Regards,

Kami Huang

    Hi Kami,

    The button is used to start the BQ76920 from sleep, it powers up, provides the REGOUT which would power the MCU.  The push button is a simple concept but requires manual action.  See the application note bq769x0 boot switch alternatives for some options.  With the BQ76200 high side switch a boot signal is needed which is powered externally or is related to PACK+.  See TIDA-00792 for an example.
