3 Summary

In conclusion, both TCAN28xx-Q1 and TCAN29xx-Q1 are CAN system basis chips that can be used in the same systems (apart from a few things like ASIL rating) if the designer fully understands the differences between the two. Consulting this app note in conjunction with the device datasheet and functional safety documentation will make that process easy.
