Reduced Electromagnetic Emission
The bus driver has an implemented control to reduce the electromagnetic emission (EME). This
is achieved by controlling the symmetry of the slope, resp. of CANH and CANL.
Overtemperature
The driver stages are protected against overtemperature. Exceeding the shutdown temperature
results in deactivation of the driving stages at CANH/L. To avoid a bit failure after cooling down,
the signals can be transmitted again only after a dominant to recessive edge at TxD.
Figure 3
overtemperature condition causes the transmission stage to deactivate. After the overtemperature
condition is no longer present, the transmission is only possible after the TxD bus signal has
changed to recessive level.
