Gate driver ICs come with embedded microcontroller

TOSHIBA ELECTRONIC DEVICES SmartMCD Series TB9M003FG gate driver ICs with embedded microcontroller (MCU) are suitable for sensorless control of three-phase brushless dc motors used in automotive applications. Device combines a microcontroller (Arm Cortex-M0), flash memory, power control functions and communications interface functions into a gate driver that controls and drives N-ch power MOSFETs for three-phase brushless dc motor drives. This integration reduces system sizes and component counts while realizing advanced and complex motor control for a wide variety of automotive motor applications. Product also incorporates firm’s proprietary vector engine, hardware for sensorless sinewave control, reducing the load on the microcontroller, and the size of the software.
