Product Description

The MP6500 is a stepper motor driver with a built-in translator and current regulation. Current sensing is internal, requiring no external sense resistors. High integration and a small QFN package make the MP6500 a space-saving and cost-effective solution for bipolar stepper motor drives. 

The MP6500 operates from a supply voltage of up to 35V and can deliver motor current up to 2.5A, depending on the package and thermal conditions. The MP6500 can operate a bipolar stepper motor in full-, half-, quarter-, or eighth-step modes. Internal safety features include over-current protection (OCP), input over-voltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown. 

The MP6500 is available in QFN-24 (5mmx5mm) and TSSOP-28 EP packages.
