8.2.7.5.2 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 and BATFET are disabled and BATFET_DIS bit is set to reduce leakage current on PMID. Once temperature returns within thresholds, the host can clear BATFET_DIS bit or provide logic low to high transition on QON pin to enable BATFET and boost mode.
