DRV8881: DRV8881PRHRT odd behavior

Part Number:DRV8881

Dear Team,

Could you please help with the following customer question ?

I've encountered a strange behavior of the servo driver (DRV8881PRHRT):

1. 1. For some reason its 2^nd channel refuses to issue PWM signal of more than ~60% duty cycle , although the input signal has a higher value (see attached scope traces)
   2. The design (also attached) is a 2^nd version of a board; In the original version there was no such issue
   3. No design changes where done in the servo circuit
   4. The first channel and a second similar driver circuit operate flawlessly   
   5. The FAULT signal remains high during the operation

Customer has also attached schematics and waveforms.

Please contact me on the internal mail and I will send it over.

Best regards,

Nir.
