HI,
I have few question regarding DRV8701:
1) What is the minimum allowable operating PWM pulse width for DRV8701?
2) I am using 64kHz PWM frequency in my application. With DRV8701EVM (Eval-board), I am seeing in consistent output (even missing pulse ) if the PWM pulse width is shorter than 8us. Please refer to attached file ( WAVEFORM-1.xlsx and Missing Pulse.xlsx) for detail.
[View:/cfs-file/__key/communityserver-discussions-components-files/38/WAVEFORM_2D00_1.xlsx:1230:0][View:/cfs-file/__key/communityserver-discussions-components-files/38/Missing-pulse.xlsx:1230:0]
May I know the reason ?
3) I am also seeing inconsistent output rise time with short PWM pulse width. Please refer to attached file:[View:/cfs-file/__key/communityserver-discussions-components-files/38/Inconsistent-Output-Rise-time.xlsx:1230:0]
May I know the reason?
