我用6伏的输入给4.2v的电池充电,一直充不上去,但是电池也可以为系统供电,因为电池没有热敏电阻,我在ts脚焊个10K并到地上,那个stat1灯就一直亮着,把电池拔了也一直亮,求解各位大佬

您好,stat一直亮说明有错误,您看一下电路是否有问题

我是在ts脚焊短接一个10k电阻倒到地,因为没有热敏电阻,所以才这样做的,这个是有问题的吗

您好,若没有NTC,TS脚可以用固定电阻将VREF分压到1.8V接到TS脚即可。You can refer to the Thermistor Comparator section on the Electrical Characteristics table in the BQ24610 datasheet. The temperature is sensed as a voltage and compared internally to comparators that have references set as a % of VREF. The EC tables have the min, typ and max values for rising and falling (hysteresis). Section 9.3.18 Temperature Qualification also explains TS functionality.
