Hi folks,

As there are on this list regularly discussions of items which are not
exactly PIC related but of "general" interest I hope there are some
people on this list which might have had the same problem regarding the
supply current of the transceiver-device.

I'm looking for a really fault tolerant CAN transceiver for 24V (!)
systems. For example the Philips's PCA82C251 seems to be quite suitable
except its high power supply current. As I read in the datasheet it
might be as high as 85mA (max. @ CAN-Bus dominat). As I would prefer
using a linear regulator this might cause tremendous high power
dissipation of the voltage regulator!

Due to the fact that our application should be able to communicate even
with one bus line continuesly shortened it would be more convenient for
me using a CAN transceiver for 24V systems with lower max. power
consumption. Maybe anyone know whether there is a more intelligent
device available with reduced power dissipation in case of bus shorts?

Any hint will be appreciated highly!

Best regards,
Marc Schmaeche
