Hello,

we plan to design a new motor control ecu for various motors in mobile robotics.
The demand of functional safety arises in these use cases.

Is there official support from Infineon covering functional safety topics?

Is a safety library available like that for the aurix family?

E.g. Hitex is offering some libraries for XMC1xxx, but is this also suitable for the combination chip imd70xA?

Dear @florian_loeff,

Good Day!

Thanks for posting your question in Infineon Community.

Sorry for the delay in response.

 

We don't have existing solution for functional safety of IMD700A. But Hitex solution for XMC1xxx should be fine. But you need to integrate into IMD700A.

Thank you!

 

Best Regards,
Vinay

Hello Vinay,

Thanks for your reply.
A related question would be on the nBRAKE signal.

In the figure 26 of the IMD701A Datasheet the signal is driven by a pullup to high.
In the figure 67 of the IMD701A Datasheet it looks the way that the gate driver can pull this line low.
We would also like to pull the line low from outside in case of emergency.

Now the question is what happens if the XMC1404 Pin is configured as output high by mistake or software bug?
Is the high side driver of the Pin P1.3 deaktivated in this chip? Or may occur damage if P1.3 drives high and the gatedriver or an external device pulls the nBRAKE line low?

Thanks for your support,

Florian
