EMC
Figure 18 shows a recommended application circuit for
automotive applications (wheel sensing f
It provides a protection interface to meet Electromagnetic
Compatibility (EMC) standards and safeguard against
voltage spikes Table 1 lists the tests which are applicable
to this circuit and the achieved class of functional status.
Protection against ‘load dump’ (test pulse 5 according to
“DIN 40839” ) means a very high demand on the protection
circuit and requires a suitable suppressor diode with
sufficient energy absorption capability.

The board net often contains a central load dump
protection that makes such a device in the protection
circuit of the sensor module unnecessary.
Tests for electrostatic discharge (ESD) were conducted in
line with “IEC 801-2” to demonstrate the KMI15/4’s
handling capabilities. The “IEC 801-2” test conditions were:
C = 150 pF, R = 150 , V = 2 kV.
Electromagnetic disturbances with fields up to 150 V/m
and f = 1 GHz (ref. “DIN 40839” ) have no influence on
performance.
