Key Document


TIDA-00786 is a small footprint brushed DC motor controller that has a fixed 100% duty-cycle speed input and variable current regulation.  The DRV8871’s integrated current sensing feature allows the design to utilize a standard potentiometer allowing the user to vary the current limiting level quickly between a range of motors that can be powered by a 12- to 24-V input.

  • 12- to 24-V Operation
  • Fixed speed input at 100% duty-cycle
  • Onboard 100-mill header for quick change of motor connections
  • DC Barrel plug allows for universal connections from different commercial power supplies
  • Durable potentiometer equipped to handle extended use
  • Internal current regulation allows for extremely small footprint
  • Variability of RILIM reduces test time for determining proper end application current regulation level
