Hi Team,
We are using the BQ20Z95 in our battery pack design as below;
Battery Design Configuration : 4 Series
Non Removable (NR=1)
Sense Resistor =10 mOhm
Default Setting used related to Short Circuit parameters.
From an initial open circuit battery pack condition, a short circuit is applied to the battery pack. Initial short circuit detection seems to work properly but when it tries to recover (after the Current Recovery Time) while the battery pack is still in short circuit condition, the Dsg FET will oscillate at 20mS cycle.Same situation is observed when the Dsg FET is turned ON (from OFF condition with short circuit applied) using the SBS command.
Attached is a much more detail description of the issue.
Regards,
Prasanna Dayala.
