Toshiba Electronics Europe GmbH has initiated shipments of engineering samples of the TB9M040FTG SmartMCD™ device. This product integrates a microcontroller (MCU) and power MOSFETs to directly drive three-phase brushless DC (BLDC) motors in compact automotive systems up to 40W.
Rising vehicle electrification increases demand for small BLDC motors in electric valves, HVAC dampers, pumps, fans, and grille shutters. These applications require high integration to reduce component count and minimize ECU size.
The TB9M040FTG incorporates a 32-bit Arm® Cortex®-M23 core, flash memory, a three-phase BLDC driver with integrated MOSFETs, a 5V supply for external sensors, and a LIN transceiver—all within a 6mm × 6mm VQFN36 package.
A dedicated Vector Engine (VE) coprocessor accelerates field-oriented control (FOC), shortens FOC cycle times, reduces CPU load, and minimizes software footprint. Back electromotive force (BEMF) detection enables sensorless square-wave control.
The device meets AEC-Q100 Grade 0 and supports ASIL-B, targeting automotive applications with medium functional safety requirements. Integrated protection includes undervoltage, overvoltage, overcurrent, thermal shutdown, charge pump monitoring, and drain-source voltage (Vds) detection for high- and low-side MOSFETs.
Toshiba will extend the SmartMCD™ series to enable compact, efficient automotive motor control systems.
