LMD18245 bipolar stepper motor controller circuit

Using the LMD18245 full-bridge power amplifier that incorporates all the circuit blocks required to drive and control current in a brushed type DC motor or one phase of a bipolar stepper motor can be designed various motor applications.
The LMD18245 controls the motor current via a fixed off-time chopper technique.
An all DMOS H-bridge power stage delivers continuous output currents up to 3A (6A peak) at supply voltages up to 55V.

Motor controller circuit diagram using LMD18200 motion controller

Using the LMD18200 3A H-Bridge designed by National Semiconductors for motion control applications we can design a very simple motor controller electronic project . 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.
