Part Number: DRV8353RS-EVM

Hi team,

Here's an issue from the customer may need your help:

When no load, output PWM waveform drives MOSFET, MOSFET and chip are hot. When disable the chip or MCU does not output PWM waveform, the chip normally does not heat, the image is DRV configuration and the waveform of  SHx and GHx.

Could you help check this case? Thanks.

Best Regards,

Cherry
