Part Number: DRV8434
Other Parts Discussed in Thread: DRV8452, DRV8461, DRV8462

Tool/software:

In my design I am using a performance motion device IC(Magellan MC54113).
My stepper motor maximum current is 3A with stall detection, current limiting, over voltage protection, Communication-RS485, Input voltage (12-56), O/P configuration- High Side, Low Side, Step/Direction.
Kindly provide alternate for above part in TI with better performace.

    Hello Elavarasan,

    For stepper currents > 3 A the following drivers are a good fit, DRV8452 5 A IFS (I full-scale) in DDW-44 package ad 4 A IFS in PWP-28 package. Other devices such as the DRV8461 and the DRV8462 are also a good fit. The DRV8462 in DDW package supports up to 5 A IFS in DDW package and up to 10 A IFS in DDV package with top mounted heatsink. 

    The DRV8461, DRV8462 have EVM available for evaluation with the actual stepper motor. Thank you.
