The LMD18201 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. The H-Bridge
configuration is ideal for driving DC and stepper
motors. The LMD18201 accommodates peak output …
