9.2.7.5.2 Cold/Hot Temperature Window in Boost Mode
For battery protection during boost mode, the device monitors the battery temperature to be within the VBCOLDx to VBHOTx thresholds unless boost mode temperature is disabled by setting BHOT bits to 11. When temperature is outside of the temperature thresholds, the boost mode is suspended. Once temperature is within thresholds, the boost mode is recovered.
