7 Summary

Implementing FDIR in electronic designs for space missions is complex. It requires components that can withstand radiation, temperature extremes, and long mission durations—conditions that standard commercial components are not built for.

TI’s space-grade products offer integrated diagnostics and fault handling features to help designers reduce overhead. Dedicated solutions enable effective isolation and avoidance of fault propagation. TI can provide support for the full range of system recovery strategies, from a simple “switch-over” up-to complex decision making based on multiple sensor inputs.
