Notes

17.

This information is given as 6 bits and is only accurate:

• a) from 0 °C to 25 °C:

• - from 0 A to 3.875 A: +/- 375 mA

• - from 3.875 A to 7.75 A:+/- 10%

• b) outside the previous temperature range:

• - from 0 to 3.875 A: +/-625 mA

• - from 3.875 A to 7.75 A: +/-15%

• Currents higher than 7.75 A, which may be possible at low temperature, are reported as 7.75 A. Excitation Current and Die Temperature functions

are exclusive.

18.

This gives a resolution of 3.5 degrees and the accuracy is +/-10 degrees. Excitation Current and Die Temperature functions are exclusive.

Table 8. LIN byte/direction data format

For TC80310AxHWS, the MID 0x27 is reserved. Therefore, if nodes other than the 80310 are placed on the LIN bus, the MID 0x27 is

forbidden. For TC80310BxHWS, the MID 0x27 can be used on the same LIN bus.
