8.3.6.4.2 Boost Mode Thermistor Monitor During Battery Discharge Mode

For battery protection during Boost mode, the device monitors battery temperature to be within the VBCOLD and VBHOT thresholds. When RT1 is 5.3 kΩ and RT2 is 31.14 kΩ, TBCOLD default is -19.5°C and TBHOT default is 64°C. When the temperature is outside of the temperature thresholds, Boost mode is suspended. In addition, the VBUS_STAT bits are set to 000 and NTC_FAULT is reported. Once the temperature returns within the thresholds, Boost mode is recovered and NTC_FAULT is cleared.
