Hello,
I want to use more than 4 BTS7002 channels (10 exactly) in a power module distribution circuit for a race car.
Is it possible to use the hss-board-arduino.hpp shield library with more than 4 channels?
If yes how to modify it?
and if not would you have an example of code allowing to make the diagnosis without the library?

Hello,
Thankyou for posting on Infineon Community.

Yes, you can use more than 4 channels. But please confirm which Arduino board you are using in the application and does it have enough GPIO pins and ADC pins such that all the channels can be connected and controlled accordingly.
Also, are you going to use DEN pin and IS pin in your design?


Please refer the below image to know how GPIO pins and ADC pins are connected :

If the board is satisfying the part, we can look into the code modification.

Thanks and Regards,
Anshika

Thanks for your help

I would like :
4x output set combined to have 40 Amp per output
3x output single 20 Amp (see shema)

I want to use current measurement and diagnostics.

The microcontroller can be an ATSAME51 (Feather_M4_CAN) or other (Mega2560)

I have already made a first prototype but with BTS50020-1TAD without current measurement.  BTS50020-1TAD are out of stock, then i update project by a new version with BTS7002.
