REV 5.0:
Added:
4 connectors for thermistors to FET gates for precharge and discharge, and power resistors
Comparators, and an optoisolator for thermistor circuit
2 FETs on the isolating DC-DC to turn off the isolated side through firmware (normally on/closed)
2 connectors and circuitry for fans to cool motor controllers
LED on discharge circuit
Additional inputs to MCU for data logging
...
Upon further review, this was already possible through PA9, which enabled vbat_precharge_sw to the isolated DC/DC.
The circuit to shut off isolated DC/DC added isn't entirely useless. The PA9 enable pin enables vbat_precharge_sw. I used that to power a lot of the non-isolated stuff like overtemp comparators and fans. So we still have functionality in keeping those on to log with the MCU.
I think it also powers the contactor sense so it'd be nice to have that on whenever the board is on.
After further discussion, it is decided that two load switches would be the better alternative.
