Trinamic Motion Control GmbH & Co. KG, introduced the fully integrated TMC6140-LA 3-phase MOSFET gate driver that simplifies design and maximizes battery life of brushless direct current (DC) motor drives.

The TMC6140-LA 3-phase MOSFET gate driver incorporates all three bottom shunt amplifiers to provide a complete motor drive solution with 30% improved power efficiency. The TMC6140-LA allows for a simplifying design by reducing component count by half when related to comparable solutions.

The TMC6140-LA is optimized for performance over a wide voltage range. It is ideal 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.

According to the company, the key advantages of the TMC6140-LA are:

  • Simple Design
  • Longer Battery Life
  • Enhanced Diagnostics
