  • DRV8305: Radiated Emissions releated to DRV8305 Internal Clock

    Resolved
    Part Number: DRV8305 I use two DRV8305NPHPRs on my custom pcb for two BLDC motors. I tested radiated emissions about the pcb. Then I found peak emissions around 120MHz. The source of peak emissions are most likely caused by DRV8305 internal clock. Because…
