Fault-tolerant CAN transceiver

3.2. Summary
In order to properly dimension the Vcc supply of the Fault-Tolerant CAN Transceivers two parameters
have to be taken into account:
1) the average supply current
2) the peak supply current
The average supply current is needed to calculate the thermal load of the required Vcc voltage
regulator. The peak supply current may flow in case of certain bus failure conditions for a certain time
and thus has an impact on the power supply buffering.
The Vcc supply of the Transceiver is recommended to support the characteristics as follows:

The capacitive buffering needed for the transceiver depends on the systems power concept and the
regulator characteristic of the used voltage regulator chip.
In case the transceiver has a
separated
Vcc power supply independently from the microcontroller, the
peak supply current during single bus failures is relevant because here the communication medium
has to keep unaffected. The worst case dual failure situation is not relevant since here the
communication medium is completely unavailable and the transceiver does not needed to be supplied
anymore. Such systems are recommended to provide a bypass capacitance of
47 uF
in order to
withstand single wiring faults.
Depending on the regulator behaviour this capacitance may
become smaller if the regulation time constant is fast enough.
In case the transceiver’s Vcc power supply is
shared
with its host microcontroller, the peak supply
current during the worst case dual failure situation has to be taken into account. This is because the
uC has to keep a proper supply even if there is no CAN communication possible at all. Such systems
are recommended to provide a bypass capacitance of
150uF
.
Depending on the regulator
behaviour this capacitance may become much smaller if the regulation time constant is fast
enough.
This capacitance can be implemented as a separate component or alternatively through a
corresponding increase of the capacitance of the bypass capacitor being located at the Vcc voltage
regulator.
In the following, relevant cases are considered in more detail.
