Abstract: A system for controlling a high-power drive device includes a fault detection integrated circuit product configured to provide an indication of a fault condition associated with the high-power drive device to a first terminal in a first voltage domain in response to detecting the fault condition in a second voltage domain. The system includes a gate driver controller integrated circuit product configured to drive a second terminal coupled to a control node in a second voltage domain based on a control signal and an enable signal received from a third terminal in the first voltage domain. The second voltage domain is higher than the first voltage domain. The system may include a redundant fault reporting integrated circuit product or an additional fault detection integrated circuit product configured to detect a second fault condition in the second voltage domain that is different from the fault condition.
