DESCRIPTION
The LMD18245 full-bridge power amplifier 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. The multi-technology process used to build the device combines bipolar and CMOS control and protection circuitry with DMOS power switches on the same monolithic structure. 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. The DMOS power switches feature low RDS(ON) for high efficiency, and a diode intrinsic to the DMOS body structure eliminates the discrete diodes typically required to clamp bipolar power stages.
An innovative current sensing method eliminates the power loss associated with a sense resistor in series with the motor. A four-bit digital-to-analog converter(DAC) provides a digital path for controlling the motor current, and, by extension, simplifies implementation of full, half and microstep stepper motor drives.For higher resolution applications,an external DAC can be used.

I recently tested the Utsource LMD18245T integrated circuit and was very impressed with its performance. The circuit was easy to install and the instructions were clear and concise. The circuit was able to handle the high current and voltage requirements of my project with ease. The circuit was also very reliable and I had no issues with it during testing. Overall, I am very satisfied with the per
