The BQ40Z50-R5 device can permanently disable the battery pack in case of significant overtemperature on the power FET. The temperature sensor(s) can be configured to report as FET temperature in DAStatus2() by setting the corresponding flag in Temperature Mode and DA Configuration[FTEMP].
Status | Condition | Action |
---|---|---|
Normal | FET Temperature in DAStatus2() < SOTF:Threshold | PFAlert()[SOTF] = 0 |
Alert | FET Temperature in DAStatus2() ≥ SOTF:Threshold | PFAlert()[SOTF] = 1 BatteryStatus()[OTA] = 0 |
Trip | FET Temperature in DAStatus2() ≥ SOTF:Threshold for SOTF:Delay duration | PFAlert()[SOTF] = 0 PFStatus()[SOTF] = 1 BatteryStatus()[OTA] = 1 |
