DRV8800: the maximum fPWM for Logic input PWM frequency(Enable)

Hirotaka Matsumoto

Part Number: DRV8800

Hi all

Would you mind if we ask DRV8800?
How much is the maximum fPWM for Logic input PWM frequency(Enable)?Less than 50kHz?

Kind regards,

Hi Matsumoto-san,

The recommended maximum is 100kHz.

Thank you for your reply!

How much is the maximum usable duty cycle range in case of fPWM=100kHz?
We think that it depends on pulse width to ensure detection.
How much is the pulse width to ensure detection?

Hi Matsumoto-san,

Apologies for the delay. Recommended duty cycle range at 100kHz is 20% to 80%.
