①IN Register 0CH,field 3:2 is called fm_osfb,which means"output stage feedback failure behavior". Question is :how to understand feedback failure in real application scenarios?

② how understand high-side and low-side?

③what is ART mode?

Hi,

Thanks for using Infineon community.

1. First failure detection, then failure reaction, and then Error Handling. In real scenarios, for example, drain-source overvoltage, over temp., braking happened, all these failure can be detected by chip, chip gets the error message, then react according to the failure.

2. In a half bridge, the upper mosfet is high-side mosfet. the lower mosfet is low-side mosfet.

3. Do you mean UART mode? UART can be used in four different modes. Details description please see datasheet.

Thanks and BR

Steven

question 3 :not mean ART.maybe I have found the meaning of ART.  In User_manual,ART  means rectification mode?

Hi,

Could you upload the User_manual in your hand, let me double check.

BR,

for Example,page 24 in user manual:

"art_fi:rectification filter time"

so,i guess ART mode means rectification mode.
