The charger provides a single thermistor input (TS) for battery temperature monitor. The TS pin can be ignored by setting TS_IGNORE = 1. When the TS pin feedback is ignored, the charger considers the TS is always good for charging and OTG modes, and TS_STAT will always report TS_NORMAL. The TS pin may be left floating if TS_IGNORE is set to 1.
When TS_IGNORE = 0, the charger adjusts the charging profile based on the TS pin feedback information according to the configurable profile described in Section 7.3.5.4.1. When the battery temperature crosses from one temperature range to another, TS_STAT is updated accordingly, and the charger sets the FLAG bit for the newly-entered temperature range, unless it is TS_NORMAL, which has no FLAG. If TS_MASK is set to 0, any change to TS_STAT, including a transition to TS_NORMAL, will generate an INT pulse.
