DRV8873-Q1: Input pulse width to ensure detection

Hi all

Would you mind if we ask DRV8873-Q1?

On the DRV8870's datasheet, there is the description "The voltages applied to the inputs should have at least 800 ns of pulse width to ensure detection."

So, does DRV8873-Q1 have the same restriction for input?
If it has the same restriction, how much is it? 800ns?
And then, is this input width restriction for only DRV8870?

As the background of this question, we would like to know the usable duty cycle range which depends on PWM frequency.

Kind regards,
