Dear experts, please refer to my schematic and battery protect Thermistor SPEC. On my schematic, I turn off the safety timer function of bq24610. So, I set the TTC Pin to "HI" level. You can find on my schematic, the TTC pin is connected to VREF. Is this way will disable the battery temperature protect function of bq24610? Because on my experiment, when the cell's temperaturre is fallen to -4°C, the bq24610 still keeps on charging mode. It will not turn off the charging function when the cell is at -4°C. On my schematic, the TS pin resistor are set to 78.7K ohm and 649K ohm(Follow the formula on bq24610 datasheet, page21). I wish the charging temperature range is from 0°C~45°C. Could you give me some comment about this issue? Thanks.
