DESCRIPTION

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.
