As per TRM, OCC condition will be released when PACK <= TOS - DELTA . This make sense only for HIgh side design.
For low side Mosfet design, PACK pin is connected to BAT pin though 10K resistance. It will make PACK pin voltage always equal to TOS.
So for releasing from OCC condition, only criteria will be "Recovery Threshold & Time" . Please correct me if I am wrong.
Thanks a lot for support.
