FUNCTIONAL DEVICE OPERATION
PROTECTION AND DIAGNOSIS FEATURES
PROTECTION AND DIAGNOSIS FEATURES
ELECTROSTATIC DISCHARGE (ESD)
The 33399 has two Human Body Model ESD values. All
pins can handle ± 4.0 kV. The LIN bus pin, with respect to
ground, can handle ± 5.0 kV.
ELECTROMAGNETIC COMPATIBILITY
RADIATED EMISSION ON LIN BUS OUTPUT LINE
Radiated emission level on the LIN bus output line is
internally limited and reduced by active slew rate control of
the output bus driver.
Figure 11
shows the results in the
frequency range 100 kHz to 2.0 MHz.
ELECTROMAGNETIC IMMUNITY (EMI)
On the LIN bus pin, the 33399 offers high EMI level from
external disturbance occurring at the LIN bus pin in order to
guarantee communication during external disturbance.
On the WAKE input pin, an internal filter is implemented to
reduce false wake-up during external disturbance.
NOISE FILTERING
Noise filtering is used to protect the electronic module
against illegal wake-up spikes on the bus. Integrated receiver
filters suppress any high-frequency (HF) noise induced into
the bus wires. The cut-off frequency of these filters is a
compromise between propagation delay and HF
suppression.
