This is Ram, We are migrating the motor driver from DRV8825 to DRV8428, We worked on the DRV8428EVM, But we made a separate PCB for the DRV8428. We can't able to run the motor. IC seems to be in good condition.

I have attached the schematic of the PCB. Can you ensure, if there is any change? we need to know.......

Hello Ram,

Ensure the driver is enabled correctly via En/nFAULT pin. Section 7.3.7.1 EN/nFAULT Pin and associated Figure 7-15. EN/nFAULT Pin describes the usage of this pin. In addition be sure nSLEEP pin is at the proper logic level voltage. See table Table 7-8. Functional Modes Summary in the datasheet.
