Maximized battery life and half component count

The 3-phase MOSFET gate driver TMC6140 from ADI Trinamic simplifies design and improves efficiency by 30 percent.

The fully integrated 3-phase MOSFET gate driver TMC6140 from ADI Trinamic simplifies design and maximizes battery life of electronically commutated motor drives. The TMC6140 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 is optimized for performance over a wide voltage range, making it well-suited for servo motors, BLDC motors and permanent magnet synchronous motors (PMSM). The three-phase gate driver is equipped with charge pumps for both the high- and low-side drivers, statically stabilizing the gate voltages of external MOSFETs with up to 100A of coil current. Offered in a 36-pin QFN package with 5 x 6 mm, the TMC6140 is a flexible solution for 5V to 30V DC and 0.5A or 1.0A gate current 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.
