EMC−Characteristics: Conducted Susceptibility
All EMC−Characteristics are based on limited samples
and no part of production test according to 47A/658/CD
IEC62132−4 (direct Power Injection).
Test Conditions
Supply Voltage V
in
= 12 V
Temperature T
A
= 23°C + −5°C
Load R
L
= 100 W
Direct power Injection
33d Bm (Note 1) forward power CW for global pin (Note 2)
17 dBm (Note 1) forward power CW for local pin (Note 3)
Acceptance Criteria
Amplitude Dev. max 4% of Output Voltage
Reset outputs remain in correct state + −1 V
1. dBm means dB milli−Watts, P
(dBm)
= 10 log
(P
(mW)
)
2. A global pin carries a signal or power which enters
or leaves the application board
3. A local pin carries a signal or power which does
not leave the application board. It remains on the
application board as a signal between two
components
