Full Bridge Motor Drivers

A half bridge driver uses two switching elements and can only drive current in one direction through a load. A full bridge (H-bridge) driver uses four switching elements and enables bidirectional current flow, making it essential for applications requiring motor reversibility. Full bridge drivers are more complex but significantly more versatile for DC and stepper motor control.

Bridge drivers are integrated circuits that control the switching elements in H-bridge or half-bridge topologies to drive inductive loads such as motors, solenoids, and actuators. They provide the gate or base drive signals needed to switch power transistors efficiently, while incorporating protection features like shoot-through prevention, thermal shutdown, and overcurrent detection.

LEVEL SOLUTIONS supplies full bridge motor driver ICs from leading manufacturers including Allegro MicroSystems, Toshiba (TB6xxx series), ROHM (BD-series), Hitachi, and Sprague. Each manufacturer offers distinct product lines optimized for automotive, industrial automation, robotics, and consumer electronics applications in commercial and Mil-spec grades.

Yes. LEVEL SOLUTIONS stocks and sources full bridge motor driver ICs in both commercial and military-specification (Mil-Spec) package types from all major manufacturers. Mil-Spec components meet stringent environmental, electrical, and reliability standards required for defense, aerospace, and mission-critical industrial applications.

Full bridge motor driver ICs can control a variety of motor types, including brushed DC motors, stepper motors, and brushless DC (BLDC) motors. Products from Allegro MicroSystems, Toshiba, and ROHM support all three motor types, with integrated PWM current control, commutation logic, and protection circuits tailored to each motor topology.

LEVEL SOLUTIONS maintains millions of full bridge motor driver ICs in a local ESD-compliant warehouse, with most orders ready to ship the same day. For parts not held in local stock, our global supply chain network provides access to billions of additional components sourced from around the world. Specific shipping timelines are available upon request.
