When the device determines that the DSG FET should turn on from the OFF state, the device enters into PRE-DISCHARGE mode first, and then the PDSG FET is turned on. The gauge stays in this mode until any one of the following requirements is completed.
Once the gauge is out of PRE-DISCHARGE mode, the PDSG FET is turned off and the DSG FET is turned on.
