NOTE: Views on isolation methods will vary and can affect gate drive, communication interfaces and power distribution architecture. Isolated auxiliary power may come from 12V, 48V or both batteries. Isolation may only be used for gate drive interface to protect for noise but if the gate drive IC is junction isolated then there may be no requirement for discrete digital isolators. Isolation requirements between the 12V and 48V power nets can vary.
