MC4x Wake On CAN

ksilovich 5 months ago in IQANdesign updated 5 months ago 3

We are using a lot of MC41 and MC42 for some OEM (Dodge/Jeep/Chrysler) stand alone drive train kits.   We are looking to add some support for some other features, and we really need to be able to wake up the module when the CAN network becomes active.   And then shut down after the network is dead, or with an input.     


I know the MC4x line doesn't support that currently, but have you guys thought about adding something like that in?   

Or does anyone know of a low cost Wake on CAN module/relay, that can apply power to an MC4x? 

There are plenty of modules availible for the automotive world that reacts to specific CAN messages like ignition on and turns on a relay.

A few examples:

J1939 programmable: https://www.in-carpc.co.uk/products/view/cb-6-multi-output-can-bus-interface

Cheap universal: https://incartec.co.uk/product/Universal-CANBUS-Interface-SLIMKEY

Or, if you want to wakeup on *any* traffic it would be easy to build with MAX3053 like https://www.homeconstructor.net/en/self-made-can-activity-indicator

Then ofcourse you need to somehow make the bus completely silent otherwise it will never sleep.

I would need a wake on any traffic solution, but dont have the time to build my own board to do that.  Need a off the shelf proven solution for this.
