9.13 EFUSEV
The system samples the input current of the main service load branch (12 V), converts the current
to a linear voltage analog signal, and sends the signal to the EFUSEV pin of the PSU.

PSU side: OD gate output. There is no pull-up on the PSU
side, or the DSP directly outputs the signal through a
series resistor.
System side: After the signal is pulled up to 3.3 V, it is
sent to the system reversely through the MOSFET.
