Toshiba Begins Sample Shipments Of Automotive Brushless DC Motor Control Device
KUALA LUMPUR, May 14 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has started shipping engineering samples of "TB9M040FTG", a motor control device with built-in power MOSFETs for three-phase brushless DC motor drives.
The device is the latest addition to Toshiba‘s "SmartMCD" series of motor control devices, which integrates a microcontroller (MCU) and a motor driver and is suitable for controlling small motors used in automotive equipment.
According to Toshiba in a statement, electrification of vehicle moving parts continues to advance, driving demand for small three-phase brushless DC motors used in applications such as electric valves, dampers and flaps in heating, ventilation, and air conditioning (HVAC) systems, as well as grille shutters.
This trend is also increasing demand for devices with fewer components and smaller electronic control units (ECUs), alongside field-orientated control (FOC) support functions and sensorless control that enable more advanced motor control while reducing CPU load.
Housed in a compact VQFN36 package, Toshiba’s TB9M040FTG integrates an MCU, flash memory, a motor driver capable of directly driving three-phase brushless DC motors, a high-side driver for power supply applications, and a local interconnect network (LIN) transceiver.
It also incorporates a Vector Engine (VE) integrating Toshiba’s proprietary hardware, which helps to reduce CPU loads in FOC‑controlled motor applications and contributes to smaller software programmes, alongside featuring a back electromotive force (BEMF) detection function that enables sensorless square-wave control.
Toshiba said the combination of these functions enables system downsizing, reduced component count, and advanced motor control for a wide range of small automotive motor applications.
Toshiba will continue expanding its SmartMCD lineup with solutions designed for automotive motor drive systems, contributing to further system miniaturisation and efficiency improvements.
