Product Description

The MP6600 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 MP6600 a space-saving and cost-effective solution for bipolar stepper motor drives.
The MP6600 operates from a supply voltage of up to 35V and can deliver motor currents up to 1.5A (depending on PCB design and thermal conditions). The MP6600 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 MP6600 is available in a QFN-24 (4mmx4mm) package.
