Is the BQ25620/BQ25622 suitable for scenarios where a battery is permitted to be removed/attached while VBUS is powered?
Out of curiosity, I've tried disconnecting and connecting a battery while the BQ25620/BQ25622 was powered by VBUS, the MCU can use the inbuilt ADC features to determine the presence of a battery, and it does seem to work well at least for a few tries, but I am unsure if this is advisable for production applications.
I should also note that I did not (yet) try unplugging the battery during a charge cycle, might this be a problematic case, or would it gracefully terminate the charge?
Thank you Ning, this is good to know that some protection is necessary.
Does TI offer a hot swap controller that is well-suited for use with the BQ2562X?

Hey Nicholas,
If you do submit and get a recommendation for the hot swap controller from TI could you please also post the link here? I'd also be interested in such solution.
Thanks & BR,
