1) The limit is given by the performance during CANH to ground failures, which very much depends
on the size and type of cable used.
2) The limit is given by the wake-up capability during CANH to ground failures, which very much
depends on the values of the distributed terminations across the network. Therefore, exact figures
of system size cannot be given.
3) With CANH to VBAT failures the delay of the dominant edge is increased. The maximum speed
strongly depends on the inductance of the cable used.

1) In case a module looses its battery connection, a reverse power supply of this module via the CAN
Bus lines is prevented. For the PCA82C252 and the TJA1053 an external diode at the battery pin
of the Transceiver is required. This diode is required additionally to the control unit’s polarity
protection diode typically implemented at the battery connector of the entire module.
