BQ24610在充电过程中，当测得壳温80℃左右时，会出现突然的停止充电的现象，当壳温下降至70摄氏度时，又会恢复充电。TS脚是通过两个10K电阻分压（VREF)，应该没有触发TS脚的温度保护。 请问这种情况是触发什么机制了吗？</description><category

https://www.ti.com.cn/cn/lit/ds/symlink/bq76905.pdf TS建议运行条件如下截图， 当施加0.65V至1.2V的脉冲时，TS引脚可用于唤醒设备。 而绝对最大额定值是，超出绝对最大额定值 的运行可能会对器件造成永久损坏，请看一下下面（1）。 2， BQ76905的 温度保护是独立于电流检测的，是不支持温度+电流联合触发的。</description></item><item><title>论坛文章:RE: TPS7B63-Q1:

如题，我正在使用BQ76905，我想使用他的TS上升沿唤醒，测试过确实可以从shuntdown模式唤醒。我的电路是BQ的TS pin直接接到工具外部，使用时会有3.3V左右的电压。所以我想知道长时间给BQ的TS pin高电压（3.3V、2.7V，2.1V)会对BQ有损害吗？ 还有我发现BQ的温度报警，只要温度超出阈值，无论是否有充电放电电流，BQ的Safety Alert B寄存器对应标志位都会修改，这会导致Alert引脚输出低电平(为了及时知道Alert,所以我这样配置)。比如我的放电温度阈值分别是70℃和-20℃，充电的阈值分别是50℃和0℃，那么60℃下，Alert 引脚一直低电平，我无法从Aler引脚的下降沿中即使获取BQ的变化，这有办法改成电流和温度同时满足条件，然后再开始Alert吗？</description><category
