3A, 55V H-Bridge

3A, 55V H-Bridge - LMD18200

Recommended alternative parts

  • DRV8840  -  The DRV8840 provides better thermal efficiency and a smaller package
  • LMD18201  -  LMD18200 Without Current Sensing Circuitry
  • LMD18245  -  Has Current Sensing Circuitry And Digital (4 Bit DAC) Control Of Motor Current


The LMD18200 is a 3A H-Bridge designed for motion control applications. The device is built using a multi-technology process which combines bipolar and CMOS control circuitry with DMOS power devices on the same monolithic structure. Ideal for driving DC and stepper motors; the LMD18200 accommodates peak output currents up to 6A. An innovative circuit which facilitates low-loss sensing of the output current has been implemented.
