Hi,
I have a question about the body diode of the FET inside the max22201.
Are there any specified values for reverse current?

I would appreciate it if you could get back to me right away.

I'm going to move this question to the Motor Control forum. You should get an answer here
Hi,
I cannot specifically say for this IC- but I can say generally what we do in our drivers:
The body diodes in all of our drivers are rated for the same current as the power MOSFETs themselves, as they take over part of the current in each cycle. However, body diode forward voltage is high, and therefore they lead to large power losses and conduction time needs to be kept low to avoid overheating. To address this, our power drivers actively switch on the MOSFETs when diode conduction is determined to reduce body diode current.
Hope this helps.
Thank you very much for your detailed explanation.
Your description was very helpful and clarified our understanding well.
We appreciate your support and the time you took to explain this.
Best regards,
