Product data sheet
14.2.4 Immunity against mobile phones
14.3.1 Coupled
14.3 Transients - pulses (ISO 7637-1 and ISO 7637-3)
Test level: 200 V/m with C
State: A.
In deviation of ISO 11452-5 the measurement must be taken up to 1 GHz.
Tests according to ISO 11452-2 were fulfilled.
State: A.
Definition of Global System for Mobile Communications (GSM) signal:
In deviation of ISO 11452-2 a GSM signal (definition see above) instead of an AM signal
was used.
The KMA199E is designed for a stabilized 5 V supply. To raise immunity against
non-galvanic coupled transient pulses, protection diodes are implemented into the
KMA199E.
For applications with disturbances by capacitive or inductive coupling on supply line or
radiated disturbances an application circuit is recommended. Applications with this
arrangement passed the EMC tests according to the product standard 1 (electrical
transient transmission by capacitive or inductive coupling) and standard 3 (radiated
disturbances).
The common understanding of the requested function is that an effect is tolerated as
described in
reset or diagnostic mode and comes back after disturbances. If the KMA199E operates in
normal operation mode, the test pulses are visible on the signal line. A protection circuit is
used. The KMA199E is directly supplied with 5 V.

Tests according to ISO 7637-3 were fulfilled.
Level of pulses: IV ( 60 V for pulse 3a and +40 V for pulse 3b).
