The TMC6140-LA three-phase MOSFET gate driver integrates the three lower shunt amplifiers to provide a complete motor drive solution with 30% improved energy efficiency, while simplifying the design by reducing the number of components by half compared to similar solutions.
The TMC6140-LA is optimized to operate over a wide voltage range, making it ideal for servomotors, brushless motors, and permanent magnet synchronous motors. The three-phase gate driver is equipped with pins for adding a charge pump, statically stabilizing the gate voltages of external MOSFETs in three-phase motors with up to 100 A of coil current. Offered in a 36-pin QFN package, the gate driver is a flexible solution, providing either 0.5 A or 1.0 A gate driver current for battery-powered applications from 5 V to 30 V DC, such as power tools where voltages can drop below 10 V. Integrated diagnostic and current sensing functions add functional safety while simplifying design.
