DESCRIPTION

The LMD18201 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. The H-Bridge

configuration is ideal for driving DC and stepper

motors. The LMD18201 accommodates peak output

currents up to 6A. Current sensing can be achieved

via a small sense resistor connected in series with

the power ground lead. For current sensing without

disturbing the path of current to the load, the

LMD18200 is recommended.
