DRV8711: DRV8711DPC FAULT PIN ENABLE

Part Number: DRV8711

Dear Sir,

               I am using DRV8711 to drive 4 motors on one PCB. When we do run-in mode before functional test. The fault pin active sometimes. We tried to adjustment the software and different PCB layout. But the situation still happens. Can someone help to solve this problem? Many thanks.
