Hello, I use TLE9879 Eval kit with Keil Microvision 5 for a project on control of BLDC motor in sensor-less mode.


I have a problem of BRDV CTRL1 register(Bit 28,20,12,4) and BRDV CTRL2 register(Bit 12,4) are showing 1(1=short on external FET detected). I have physically checked that there is no short in the motor or in the bridge side. I have also followed the procedure described in the datasheet "TLE987xQX-Users-Manual-13-Infineon.pdf" page number 811 to 813. But not able do so. Can you please tell us how to reset these bits.? Unless we reset these bits we will not be able to run the bridge drive(BRDV).

If any one has worked with Infineon in motor control application, please share.
