The LMD18200 is a 3A H-Bridge designed for motion
control applications. The device is built using a multitechnology 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 …
