Hi,

We are using the MC33790 for establishing an a DSI1.0 communication with a sensor module MC33793

As per the document we have provided the circuit with the VCC as 5V and Vsup as 24V while sending the data the Idle voltage is coming only up to 11.5V, not 24V can someone explain to me why the idle voltage is not reaching the expected 24V. 

Thanks 

Rakesh

Hi,

It was an issue with the DSIxF and DSIxS pin status if it is 1,0 respectively this issue occurs if it is set to 1,1 the VIDLE goes to 24V.

No it's not working with the MC33793 even after fixing the V Idle voltage issue

Does it work well if Vsup down to 11.5V?
