Other Parts Discussed in Thread: DRV2901, DRV2911
Tool/software:
Hi TI Experts,
When I was going through DRV2901 and DRV2911 data sheet for finalizing the ULC EVM, I found different frequency parameters in both piezo drivers.
DRV2901 driver:
DRV2911 driver:
Are these two parameters same? What actual it means, frequency of the PWM signal (Carrier signal) or actual frequency of the modulated signal?
If 200KHz is PWM carrier frequency, then the highest frequency of signal it can modulate is 20KHz. Is 20KHz enough to resonate the piezo in LCS? Please confirm this.
Thanks,
Selvaganapathi K,
