Overview
LMD18200 3A, 55V H-Bridge December 1999 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 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 which facilitates low-loss sensing of the output current has been implemented.
