11 What Can You Expect for TI Products

TI has three categories of functional safety products: Functional Safety-Compliant, Functional Safety Quality-Managed and Functional Safety-Capable. More information on TI's functional safety products are available here. All TI functional safety products promoted for applicability in functionally safe systems come with functional safety FIT rate and failure mode distribution (FMD).

For our most complex products like microprocessors, microcontrollers and analog signal-chain products, system integrators get a comprehensive failure modes, effects and diagnostics analysis (FMEDA) that is inclusive of the FMD based on a BFR estimated according to IEC TR 62380.

For our least complex analog products, like low dropout oscillators, operational amplifiers and voltage supervisors, system integrators receive a functional safety FIT, pin failure mode analysis and a FMD report that adhere to a standard TI-wide format.
