Hi Abhishek

I don't see VM bulk caps which is very important for motor driver device. Also need decoupling cap to VINT. Please follow the sch layout example in datasheet.

Then please note the condition to correctly entering into parallel mode your are using.

Best regards,

Hi Ashishek,

In addition to Wilson's comments, what is the VMB voltage? If it is greater than 7V, the Absolute maximum rating of the nFAULT pin is being violated.
