The Future of Analog IC Technology MP6501A 8V to 35V, 2.5A Stepper Motor Driver with Integrated MOSFETs DESCRIPTION The MP6501A is a stepper motor driver with a built-in micro stepping translator. It operates from a supply voltage of up to 35V and can deliver motor current up to 2.5A. The MP6501A can operate a bipolar stepper motor in full-, half-, quarter-, and eighth- step modes. Internal safety Features include over-current protection, input over-voltage protection, UVLO and thermal shutdown. The part has a fixed 3.3V reference output, which allows it to operate without any control power supply and work with any microcontroller. Ron of the switches is as low as 220mΩ. Current sensing is done by external resistors. The MP6501A es in a space-saving TSSOP-28 package with exposed thermal pad. TYPICAL APPLICATION Features - Wide 8V to 35V Input Voltage Range - Two Internal Full Bridge PWM Converters - Low On Resistance(HS:220mΩ; LS:220mΩ) - No Control Power Supply Required - Simple Logic Interface - 3.3 and 5 V patible Logic Supply - Full-, Half-, Quarter-, and Eighth- Step Functionality - 2.5A Maximum Output Current - Adjustable Mixed Decay Ratio - Over-Current Protection - Input OVP Function - Thermal Shutdown and UVLO Protection - Space-saving TSSOP-28 EP Package - Fault Indication Output APPLICATIONS - Bipolar Stepper Motors - Printers All MPS parts are lead-free and adhere to the Ro HS directive.
