你好,我将DSG FET Protection A 配置为0x08,当短路发生时,为什么DSG没有自动关断。

您好,请参考下面内容
See below from the TRM.
The minimum threshold for OCC is 4mV. The threshold register setting uses 2mV units, so a setting of 2 equals a 4mV threshold, see below.
To answer your question, OCC turns off the CHG FET, so the current should stop and if a load is attached the voltage on the PACK pin should drop below the recovery threshold, either allowing the device to recover from the protection. If the CHG FET does not turn off, then the current would have to drop below the recovery threshold for the duration of the recovery time in order for the device to recover.
I recommend reading Section 5.2.7 of the TRM for more information on OCC and how the device recovers from it.
您好,
OTC and OTD can be triggered at any time, even if there is no charging or discharging. As long as the thresholds are met, do you have the same temperature threshold for both?
We mention this behavior in Sections 13.6.12 Protections:OTC and 13.6.13 Protections:OTD of the Technical Reference Manual.
