1) FlexRay Physical Layer Conformance Test Specification, version 3.0.1, Chapter 5.2, static test cases, index number.
2) According to the FlexRay EPL version 3.0.1 the TLE9221SX is fully functional, including the wake-up functions, in the
specified uV_BAT range while uV_CC and uV_IO are also in their operating range.
3) Not subject to production test, specified by design
4) The extended supply range covers the load requirements according to ISO 16750-2 (load dump, jump start). This range is
not qualified for continuous, repetitive operation.
Note: Within the functional range, the IC operates as described in the circuit description. The electrical
characteristics are specified within the conditions given in the related electrical characteristics table.
