Question
STPM34 critical component analysis
We are pursuing UL3141 for Power Control Systems (PCS), this includes UL991 which is the Standard for Tests for Safety-Related Controls Employing Solid-State Devices, and it requires a critical component analysis.
In our particular design, the STPM34 is a critical component used in our PCS. To avoid hardware redesign to add sensor redundancy or a self-test circuit, we can use a "computational method" by considering component FIT data.
Typically we expect FIT data on the order of 10^6 or 10^9 hours.
- Do you have FIT data available for the STPM34, that is measured to an applicable standard?
- Does STMicro have critical component analysis data available for the STPM34?
- Does STMicro have internal resources to support customers with critical component analysis?
Kind regards,
