请教一下,如图MOS管Q3 的源极(S)和漏极(D)短接起来,然后将电池输出的正负极进行短路测试,发现Q2的栅极没有高电平,Q2没有处于导通状态,持续短路很快MOS就烧了,这是为什么,IC没有出现掉电,通讯都是正常的。

您好,请参考下面内容:
What is the voltage of the PACK+ pin when you observe this behavior? From the image you attached it appears like the gauge is trying to be in charge mode and no protections should be opening the CHG FET. However, BatteryStatus() DSG is still set. I am thinking there may not be enough current flowing for the device to exit relax mode.
