Operating Temperature
The FlexRay transceiver TLE9221SX is qualified for temperature Grade 1 (-40°C to +125°C ambient operating
temperature) according to AEC - Q100. Grade 1 according AEC - Q100 is equivalent to the ambient temperature
for class 1 T_{AMB_Class1} (CT index:53)¹⁾ defined by the FlexRay EPL, version 3.0.1.
Infineon specifies for the electrical characteristics (see Table 21) the junction temperature T_Junction. The ambient
temperature can be calculated with the power dissipation and the thermal resistance R_thJA (see Figure 49).
T_J = T_A + R_thJA x P_d
T_A = T_J - R_thJA x P_d
with:
