LMD18200
3A, 55V H-Bridge
General Description
The LMD18200 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.
Ideal for driving DC and stepper motors; the LMD18200 ac-
commodates peak output currents up to 6A. An innovative
circuit which facilitates low-loss sensing of the output current
has been implemented.
