你好！
我在使用bq76952的时候，触发了OCC，OCC恢复阈值为0。当我触发了保护后切断电流，如果此时放电FET关闭，充电FET打开，那么OCC就不会恢复，如果充放电FET都关闭，此时OCC能正常恢复，请问一下这是什么原因？
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.
