SPMU383 April 2026 BQ27Z846
The device has an undertemperature protection for cells in the DISCHARGE or RELAX state (that is, non-charging state with BatteryStatus[DSG] = 1).
| Status | Condition | Action |
|---|---|---|
| Normal | Cell Temp > UTD:Threshold OR charging | SafetyAlert()[UTD] = 0 |
| Alert | Cell Temp ≤ UTD:Threshold AND Not charging (that is, BatteryStatus[DSG] = 1) | SafetyAlert()[UTD] = 1 BatteryStatus()[TDA] = 1 |
| Trip | Cell Temp ≤ UTD:Threshold AND Not charging (that is, BatteryStatus[DSG] = 1) for UTD:Delay duration | SafetyAlert()[UTD] = 0 SafetyStatus()[UTD] = 1 OperationStatus()[XDSG] = 1 BatteryStatus()[TDA] = 0 |
| Recovery | SafetyStatus()[UTD] AND Cell Temp ≥ UTD:Recovery | SafetyStatus()[UTD] = 0 OperationStatus()[XDSG] = 0 BatteryStatus()[TDA] = 0 |
