Using the LV8741V PWM stepping motor driver IC can be designed a very simple and efficiency DC motor driver electronic project .
As you can see in the circuit diagram , this electronic project require few external electronic parts . The maximum output current that can be provided by this PWM current-control stepping motor driver IC is up to 1.5 ampere .
This DC motor controller circuit shown in this schematic use the L620x motor driver .
The L620x is a monolithic full bridge switching motor driver realized in the new Multipower-BCD technology which allows the integration of multiple, isolated DMOS power transistors plus mixed CMOS/bipolar control circuits and is available in many versions : L6201 /1PS/2/3 .
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.
