DO-254/ED-80 defines two categories of hardware items.
• Complex electronic hardware.
• Simple electronic hardware.
All flight hardware needs to be classified according to a design assurance level (DAL). The standard defines five levels regarding the safety and criticality of an avionic system (A to E).
Does this 3-Phase BLDC Motor Pre-Driver with Integrated Speed Control and Commutation Logic fall into either of these two categories?
The end use for our application for a system failure is level C
Level C: The SEH associated with functions whose failure or malfunction could cause a major failure condition as determined by the system safety assessment (design assurance level C hardware) should undergo a comprehensive combination of deterministic testing and analysis that demonstrates correct operation under all possible combinations and permutations of conditions of the inputs at the pins of the device (i.e., those inputs available external to the packaging of the device). All possible states of any sequential state machines should also be tested.
