DRV8837: Chip application problem

Part Number: DRV8837

Tool/software:

At present, there is a problem that the output will have a short time jump in the process of using DRV8837 two high and low jumps at the same time. How does this problem occur and how should it be solved?

    Hi Tony,

    Thanks for contacting us via this forum. What are the traces. What is the VM and VCC voltage? Can we get traces on IN1 and IN2, OUT1 and OUT2? What load is connected to the outputs? Please share the schematic. It will be useful if we could also get a second capture showing the load current waveform measured with a current probe. For this capture one of the inputs that does not have a PWM or active input can be substituted with the current channel. Thank you.

    Regards, Murugavel
