BQ24232HA: 温度监控

Part Number:BQ24232HA

请问TS温度监控时,放电状态的监控逻辑和充电状态的监控逻辑是否一样。

Star Xu:

您好,TS接的是NTC,阻值随温度升高而迅速减小。监控逻辑是一样的。

PENG ZHANG:

还有个问题,就是放电的时候,INTC是哪里供电

规格书PAGE 21 8.3.5 Battery Pack Temperature Monitoring 第二段里只说明了充电阶段,放电阶段没有说明

During charging, INTC is sourced to TS and 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. The timers maintain their values but suspend counting. When the voltage measured at TS returns to within the operation window, charging is resumed and the timers continue counting. When charging is suspended due to a battery pack temperature fault, the CHG pin remains low and continues to indicate charging

Star Xu:

您好,INTC是芯片提供的,INTC :NTCbias current典型值是75μA
