This reference design is for a compact brushed DC motor controller that can be utilized in printers, foreign money counters and varied different private and industrial purposes.

Texas Devices TIDA-00786 is a reference design for a small motor controller. The design is appropriate for a small-footprint brushed DC motor controller that has a hard and fast 100% duty-cycle velocity enter and variable present regulation. The reference design comes with an built-in present sensing characteristic that permits the design to make the most of an ordinary potentiometer permitting the consumer to differ the present limiting degree rapidly between a spread of motors that may be powered by a 12- to 24-V enter.

The reference design comes with an inside present regulation that permits for a compact measurement. The design comes with a DC barrel plug and options an onboard 100-mill header for fast change of motor connections. The reference design additionally contains a sturdy potentiometer for controlling the velocity. It affords a hard and fast velocity enter at 100% duty-cycle and may work with an enter voltage of 12- to 24-V offering a steady present of as much as 3.6 Amps.

The reference design is cost-effective and easy to construct due to the built-in present sensing and built-in H-bridge. The reference design requires only some discrete parts used as bulk capacitance, a voltage divider to manage the 100% duty-cycle enter, and the potentiometer + collection resistor used for the variable present limiting.

Options of the Reference Design:

  • 12- to 24-V operation with as much as 3.6 Amps steady motor present
  • mounted velocity enter at 100% duty-cycle
  • onboard 100-mill header for fast change of motor connections
  • DC Barrel plug permits for common connections from totally different industrial energy provides
  • sturdy potentiometer outfitted to deal with prolonged use
  • inside present regulation permits for very small footprint
  • variability of RILIM reduces take a look at time for figuring out correct finish utility present regulation degree


This reference design has been examined by TI. The corporate has additionally supplied further assets comparable to schematics, Gerber information, and so forth.
