Powertrain Supervisory Limits Specification – Forward Direction Operation (High Voltage Side to Low Voltage Side)
• These supervisory limits are set in the internal controller and can be reconfigured or disabled through PMBus®.
• When disabled, the powertrain protections presented in the previous table will intervene during fault events.
