DRV8801-Q1: Charge Pump frequency

Part Number: DRV8801-Q1

Hello!

I was wondering what frequency the charge pump of the DRV8801-Q1 operates at? Does it move around over input voltage range, etc? Do we have that data?

Regards,

Kevin

    Kevin,

    According to my bench test result, the charge pump frequency of the DRV8801-Q1 is 162kHz.
    The charge pump frequency doesn't change when I change input voltage from 8V to 36V.
    Sorry, I cannot find this characterization data. But, generally, we can assume 20% tolerance.
