PWM Frequency for the DRV2603

Laurence Nash

Other Parts Discussed in Thread: DRV2603

Is it possible to run the DRV2603 with a 1Khz pwm signal? It wasn't clear to me if that is just too slow. This will be to drive an LRA haptic for 0 to 100% duty. Sorry if the info is out there, I did search.

Thank you,

Hi, Laurence:

in the data sheet, it says the input frequency range is 10KHz~250KHz.

"with Input PWM frequency within the input range (10 kHz to 250kHz) will automatically produce the correct resonant output frequency."

Thank you very much, don't know how I missed it. I think I saw somewhere that any pwm signal would work, so it must have been wishful thinking!
