DRV8350: SLA SLB SLC report error

Annie Liu

Part Number: DRV8350

Hi Team,

When the customer uses DRV8350 for three-phase BLDC drive, the error item is basically the three-phase SLA side after debugging until now. The low-end waveform has been measured without overshoot and negative pressure. In the last test, an error was reported at three times at the same time. IDRIVE currently sets the maximum. Customer would like to how to resolve this issue?

Thanks,

Annie

    Hey Annie,

    Can you provide some waveforms or fault names related to "SLA side debugging"?

    If you're talking about a VGS_Lx faults, then can you please provide the GLx and SLx waveforms and the current TDRIVE setting?

    Does lowering the IDRIVE solve the problem?

      

    Best,
