2.15 SBS Host Watchdog Protection

The BQ41Z90 device can check periodic communication over SBS and prevent usage of the battery pack if no valid communication is detected.

Status Condition Action
Trip No valid SBS transaction for HWD:Delay duration SafetyStatus()[HWDF] = 1
OperationStatus()[XCHG] = 1
Recovery Valid SBS transaction detected SafetyStatus()[HWD] = 0
OperationStatus()[XCHG] = 0
