Other Parts Discussed in Thread: BQ25798
Tool/software:
Hello,
I would like to understand how the BQ25792 behaves when it operates with a detached battery (e.g. user detach or battery fault protection detach). Will undervoltage protection kick in and shut down SYS due to a floating BAT pin?
And if so, is there a simple way to mitigate this behavior (I assume spoofing battery capacitance by adding a huge polymer)? In other words, is a battery (capacity on BAT) mandatory for the BQ25792 to operate correctly? If I remember correctly, the BQ25798 features a proper no-battery detection circuit (which one main reason why I question the robstness of BQ25792 in this regard).
Best regards,
Brian
