1) According to 7637-1 the supply switched “OFF” for t = 200 ms
2) According to 7637-1 for test pulse 4 the test voltage shall be 12 V ± 0.2 V. Measured with R_M = 75 Ω only.
Mainly the current consumption will decrease. Status C with test circuit 1.
3) Applying in the board net a suppressor diode with sufficient energy absorption capability
Note: Values are valid for all TLE4941C/42C types!
