BQ24075T 充电异常

Hi
During charging, the voltage at TS is continuously monitored. If, at any time, the voltage at TS is outside of the operating range (VCOLD to VHOT), charging is suspended.
VCOLD = 0.25 X VIN
VHOT = 0.125 X VIN
你可以实际测试一下TS脚电压是否合适？或者说按照你现有的配置， 分压比率是否在0.125~0.25范围内，应该是超出了。

您将R5/R6改成200K/49.9K时，TS monitoring function被禁止，当TS pin脚电压超过VCOLD to VHOT时，将暂停充电，您可以参考datasheet 9.3.12 Battery Pack Temperature Monitoring。

目前我串了一个100K的电阻到TS。
