描述 Description

The MP6500A is a stepper motor driver with a built-in translator and current regulation.? Current sensing is internal and requires no external sense resistors. High integration and a small package size make the MP6500A a space-saving and cost-effective solution for bipolar stepper motor drives.

The MP6500A operates from a supply voltage of up to 35V, and can deliver motor currents up to 2.5A (depending on PCB design and thermal conditions). The MP6500A 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 MP6500A is identical to the MP6500, except the current setting is accomplished with a voltage input instead of a resistor to ground.

The MP6500A is available in QFN-24 (5mmx5mm) and TSSOP-28EP packages.
