DRV8353: DRV8353H Debugging issues

Part Number: DRV8353

Hi TI expert

I am using DRV8353H. Under no load condition,In 6 PWM mode of single power supply, the output waveform of GHX can be output as required, but the output waveform of GLX is wrong. According to the requirements, the output signal of GLX is opposite to that of GHX.

Please help to check. Thanks a lot.

Best regards,

Thomas

    Thomas,

    Please send us a scope image showing your inputs (INHx/INLx) and gate outputs (GHx/GLx) of one of the phases. It's best if you can include all four signals in one plot or at least one of the inputs and outputs if you have a two channel scope (INHx/GHx for example).

    Regards,
