TRINAMIC's fully integrated TMC6140-LA 3-phase MOSFET gate driver that simplifies design and maximizes battery life of brushless DC motor drives.

Trinamic Motion Control GmbH & Co. KG, now part of Maxim Integrated Products Inc., has launched the fully integrated TMC6140-LA 3-phase MOSFET gate driver that simplifies design and maximizes battery life of brushless DC motor drives.

The TMC6140-LA 3-phase MOSFET gate driver integrates all three bottom shunt amplifiers to provide a complete motor drive solution with 30-percent improved power efficiency, while simplifying design by reducing component count by half when compared to similar solutions.

The TMC6140-LA is optimized for performance over a wide voltage range, making it well-suited for servo motors, brushless motors and permanent magnet synchronous motors. The three-phase gate driver is equipped with pins to add a charge pump, statically stabilizing the gate voltages of external MOSFETs in three-phase motors with up to 100A of coil current. Offered in a 36-pin quad-flat no-leads (QFN) package, the gate driver is a flexible solution offering 0.5A or 1.0A gate driver current for 5V to 30V DC battery-powered applications, such as power tools where voltages can drop below 10V. Integrated current sense and diagnostics features add functional safety while simplifying design.

“The integrated current sense and diagnostics features are key for enabling functional safety without adding complicated circuitry or additional components to any system’s design,” said Michael Randt, founder of Trinamic Motion Control. “This allows engineers to increase efficiency by 30 percent with minimal effort.”
