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.
