Motor MCU integrates driver and control functions
Toshiba is sampling the TB9M040FTG motor control device, which integrates an MCU and motor driver for controlling small automotive motors. Part of the SmartMCD series, it supports single-channel motor drive currents up to 2 A, enabling direct drive of three-phase brushless DC motors used in electric valves, HVAC dampers, flaps, and grille shutters.
In addition to an Arm Cortex-M23 processor core running at up to 40 MHz and the motor driver, the TB9M040FTG incorporates flash memory, a 5-V high-side driver for power-supply functions, and a power supply that operates at automotive battery voltage levels. It also integrates a LIN transceiver for ECU communication.
The device features a hardware vector engine that offloads field-oriented control (FOC) processing, helping reduce CPU load and software size. Back-EMF detection enables sensorless square-wave control.
All functions are integrated into a compact VQFN36 package, reducing component count in automotive equipment. The TB9M040FTG is compliant with AEC-Q100 Grade 0 and ASIL-B requirements.
