In this case, termination is temporarily disabled and the charging safety timer is counted at half the clock rate. Figure 29. Battery Charging Profile Thermistor Qualification The charger device provides a single thermistor input for battery temperature monitor. Cold/Hot Temperature Window The device continuously monitors battery temperature by measuring the voltage between the TS pin and ground, typically determined by a negative temperature coefficient thermistor and an external voltage divider. The device compares this voltage against its internal thresholds to determine if charge or boost is allowed. To initiate a charge cycle, the battery temperature must be within the VLTF to VHTF thresholds. During the charge cycle the battery temperature must be within the VLTF to VTCO thresholds, else the device suspends charging and waits until the battery temperature is within the VLTF to VHTF range. 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 (REG06[3:2]) to 11. When temperature is outside of the temperature thresholds, the boost mode is suspended and REG08[7:6] bits (VBUS_STAT) are set to 00. Once temperature returns within thresholds, the boost mode is recovered. Figure 30.
