AMIS-30660 - Power Dissipation in Case of Bus Failure
■The AMIS−30660 high speed CAN transceiver is designed to withstand bus failures. Without any damage to the IC the CANH or CANL line may be shorted to ground,V-CC or the battery supply. However in some bus failure conditions an increase in power dissipation might occur.This will lead to a rise in junction temperature.
■Two bus states can be distinguished: recessive and dominant. In both states both CANH and CANL can be shorted to GND, V-CC or V-BAT. In this application note we are investigating the worst case conditions therefore short to V-CC is not discussed.
