MP6501AGF-Z

MP6501A 8V to 35V, 2.5A Stepper Motor Driver with Integrated MOSFETs The Future of Analog IC Technology 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 comes in a space-saving TSSOP-28 package with exposed thermal pad.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB.
