TMC6140-LA 3-Phase MOSFET Gate Driver

TRINAMIC’s fully integrated TMC6140-LA simplifies the design of high-performance brushless DC motor drives and improves efficiency by 30 percent

Image of TRINAMIC’s TMC6140-LA 3-Phase MOSFET Gate DriverTRINAMIC’s TMC6140-LA fully-integrated 3-phase MOSFET gate driver helps to simplify designs and maximize the battery life of an application. Providing a complete solution, the BLDC gate driver integrates bottom shunt amplifiers for 30% improved power efficiency while reducing the component count by 50% compared to similar solutions.

Developed for servo motors, brushless motors, and PMSM motors, the chip’s design works over a wide voltage range. Charge pumps statically stabilize the gate voltages of external MOSFETs up to 100 A coil current, for both the low-side drivers and gate drivers. For applications at 15 V or lower the switching regulator output can be used to stabilize the power supply. The TMC6140 maintains the output signals to ensure consistent operation and extended battery life. Integrated shunt amplifiers provide current sensing for status information, while an analog programmable short detection and diagnostic output reports status back to the host.
