LMD18201
3A, 55V H-Bridge
General Description
The LMD18201 is a 3A H-Bridge designed for motion control
applications. The device is built using a multi-technology pro-
cess 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 step-
per motors. The LMD18201 accommodates peak output cur-
rents 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 cur-
rent to the load, the LMD18200 is recommended.
