PWM Driver 5A

Nick Pridham 7 years ago in Master modules / MC4x updated by Gustav Widén (System support) 7 years ago 1

Has anyone had any experience whereby they have used a single IQAN PWM out with a 5A load ?  The data sheets say "no" but I am just wondering if this is possible if the number of outputs used simultaneously, is controlled.


I moved the question to MC4, as I am assuming this is the modules you are asking about? 

In the IQAN-MC4x user manaul, we have documented parallel connection of high side outputs when used as DOUT. 

The same configuration of pins when configured as PWM out is not listed. 

If you limit the parallel connections to these pin combination (e.g. OUT_31 in parallel with OUT_32) , make sure the PWM frequency is set identical, and ensure the two PWM out channels command the same MR (use the same input and the same min, max and slopes), then running them in parallel should work. 

But I have not seen any test results on this connection.
