Efficient Brushed DC (BDC) Motor Driver Solutions
Brushed DC (BDC) motors get their name from the brushes that are used for commutation. Because its speed and torque are proportional to the applied voltage and current, a BDC motor is easy to control. BDC motors are cost-effective, easy to design in and simple to control, making them suitable for use in a wide variety of applications. Our microcontrollers (MCUs), gate drivers and single-chip motor drivers enable you to create compact, robust and efficient brushed DC drives.

Gate Driver Configuration
Unidirectional Low-Side Configuration
This drive can control a BDC motor in one direction and is often used in safety-critical applications.
Unidirectional High-Side Configuration
This lowest-cost drive technique enables most applications to simply use an output pin from a PIC® or AVR® MCU to turn on the MOSFET.
Bidirectional H-Bridge Configuration
This drive can control a BDC motor in both directions.
