Powertrain Hardware Protection Specification – Forward Direction Operation (High Voltage Side to Low Voltage Side)
• These built-in powertrain protections are fixed in hardware and cannot be configured through PMBus™.
• When duplicated in supervisory limits, hardware protections serve a secondary role and become active when supervisory limits are
disabled through PMBus.
