SLUUBT5C November 2018 – June 2021 BQ40Z80
The BQ40Z80 provides recoverable protection. When the protection is triggered, charging and/or discharging is disabled. This is indicated by the OperationStatus()[XCHG] = 1 when charging is disabled, and/or the OperationStatus()[XDSG] = 1 when discharging is disabled. Once the protection is recovered, charging and discharging resume. All protection items can be enabled or disabled under Settings:Enabled Protections A, Settings:Enabled Protections B, Settings:Enabled Protections C, and Settings:Enabled Protections D.
When the protections and permanent fails are triggered, the BatteryStatus()[TCA][TDA][FD][OCA][OTA] is set according to the type of safety protections. A summary of the set conditions of the various alarms flags is available in Section 6.8.
A delay setting with 1-s granularity can have an average trigger delay equal to the delay setting plus 1.5 s.
