MP6545 Minimum PWM frequency

Motor Drivers/Sensors

Hi MPS,

What is the minimum operating PWM frequency for the MP6545?

Is a 500Hz PWM input possible?

Hello,
I am looking into this and provide feedback soon.

Best,

The datasheet mentions a charge pump instead of bootstrap capacitors. It’s very likely that there is non minimum PWM operating frequency for this part (and this it’s omission from the datasheet).
