MP6600 Datasheet | Monolithic Power Systems

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 spacesaving 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 eighthstep modes. Internal safety features include over-current protection (OCP), input overvoltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown. The MP6600 is available in a QFN-24 (4mmx4mm) package. FEATURES - Wide 4.5V to 35V Input Voltage Range - Two Internal Full-Bridge Drivers - Internal Current Sensing and Regulation - Low On Resistance (HS: 195mΩ, LS: 170mΩ) - No Control Power Supply Required - Simple Logic Interface - 3.3V and 5V patible Logic Supply - Step Modes from Full-Step to Eighth-Step - 1.5A Output Current - Automatic Current Decay - Over-Current Protection (OVP) - Input Over-Voltage Protection (OVP) - Thermal Shutdown and Under-Voltage Lockout (UVLO) Protection - Fault Indication Output - Available in a QFN-24 (4mmx4mm) Package APPLICATIONS - Bipolar Stepper Motors - Printers All MPS parts are lead-free, halogen-free, and adhere to the Ro HS directive.
