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.
