Part Number: DRV8701
Hello,
we have designed a motor control board based on a DRV8701 that works fine but we experience EMI trouble.
When DRV8701 is in sleep, there are no radiations.
When DRV8701 is driving the MOS, there are spikes radiations around it, from 50 MHz to 650 MHz, every 50 MHz. On the tracks GH and GL of the conducting MOS, we have a 150 MHz spike.
Do you have any idea to reduce these spikes amplitude ?
