Electromagnetic Compatibility
Electromagnetic Compatibility (values depends on R_M!). See Figure 9
Note:
Characterization of Electro Magnetic Compatibility is carried out on samples based on one
qualification lot. Not all specification parameters have been monitored during EMC exposure. Only
key parameters e.g. switching current have been monitored.

1) ISO 7637-2 describes internal resistance = 2 Ω (former 10 Ω)
2) Node A does not exceed 27 V clamping voltage of D2 in any case; Design target!
3) Ri=0.01 Ω
4) Testpulse4 tested for V_DD=12 V
5) A central load dump protection of 42 V is used. Us*=42 V-13.5 V
