<div id="readability-page-1">—Integrating Three-Phase Brushless DC Motor Driver and Microcontroller Enables Direct Drive of Small Automotive Motors— KAWASAKI, Japan--(BUSINESS WIRE)-- Toshiba Electronic Devices &amp; Storage Corporation (“Toshiba”) has started to ship engineering samples of &#34;TB9M040FTG,&#34; a motor control device with built-in power MOSFETs for three-phase brushless DC motor drives. The latest addition to Toshiba‘s &#34;SmartMCD™&#34;[1] series of motor control devices that integrates a microcontroller (MCU) and a motor driver, TB9M040FTG can directly drive three-phase brushless DC motors and is suitable for controlling small motors used in automotive equipment. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260513230802/en/ Electrification of the moving parts of vehicles continues to advance, and demand is increasing for small three‑phase brushless DC motors for use in applications such as electric valves, dampers and flaps in heating, ventilation, and air conditioning (HVAC) systems, and in grille shutters[2]. This is also stimulating demand for devices with fewer components and downsized electronic control units (ECUs), and for field oriented control (FOC)[3] support functions and sensorless control that secure more advanced motor control and reduce CPU loads. TB9M040FTG integrates an MCU (Arm® Cortex®‑M23 core), flash memory, a motor driver capable of directly driving three‑phase brushless DC motors, a high‑side driver that can be used for power supply purposes, a local interconnect network (LIN)[4] transceiver, and a power supply system that can operate at the automotive battery level, all housed in a small VQFN36 package (6×6mm (typ.)). 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 programs. It also features a back electromotive force (BEMF[5]) detection function, enabling sensorless square-wave control. In combination, these features enable the downsizing of automotive equipment and reduced component counts, while realizing advanced and complex motor control; TB9M040FTG can support a wide range of small automotive motor applications, and LIN communication with the ECU realizes control of small motors within automotive systems. Toshiba will continue to expand the lineup of its SmartMCD™ series equipped with the functions required for motor drives in automotive systems and to contribute to automotive system downsizing and lower component counts. <table> <tbody><tr> <td rowspan="1" colspan="1"> Notes: </td> </tr> <tr> <td rowspan="1" colspan="1"> [1] SmartMCD™: A series of automotive motor control drivers (MCDs) developed by Toshiba Electronic Devices &amp; Storage Corporation that integrate a motor driver and a microcontroller into a single device. </td> </tr> <tr> <td rowspan="1" colspan="1"> [2] Grille shutter: A shutter mechanism installed behind the vehicle’s front grille that automatically opens and closes according to driving conditions. </td> </tr> <tr> <td rowspan="1" colspan="1"> [3] Field oriented control (FOC): A typical method of vector control (a control method that independently controls motor torque and magnetic flux as orthogonal components) that uses the motor’s rotating reference frame (dq coordinate system) to independently control the magnetic flux component (d-axis) and the torque component (q-axis). </td> </tr> <tr> <td rowspan="1" colspan="1"> [4] Local interconnect network (LIN): One of the serial communication protocols primarily used for communication between electronic control units (ECUs) in vehicles. </td> </tr> <tr> <td rowspan="1" colspan="1"> [5] Back electromotive force (BEMF): A voltage induced in the motor windings as the motor rotates, generated when the rotor’s magnetic field cuts through the windings, and acting in the direction opposite to the applied voltage. </td> </tr> </tbody></table> Applications Automotive equipment <ul> <li> Small brushless DC motor applications such as electric valves, HVAC dampers, flaps, and grille shutters </li> </ul> Features <ul> <li> Integrates a motor driver for three‑phase brushless DC motors, enabling direct drive of three‑phase brushless DC motors (with built‑in motor‑drive MOSFETs) </li> <li> 32-bit MCU (Arm® Cortex®-M23), operating frequency: 40MHz (built-in low-speed and high-speed oscillators) </li> <li> Built-in memory with ECC (SEC/DED[6]) Code Flash: 80KBytes, SRAM: 4KBytes </li> <li> Built-in vector engine (VE) for FOC control and programmable motor driver (PMD)[7] </li> <li> Built-in 1-shunt resistor current sense amplifier[8], and 12-bit A/D converter </li> <li> One‑channel high‑side driver capable of supplying power to devices such as Hall‑effect sensor ICs </li> <li> Communication interfaces: LIN, UART (shared with LIN), and SPI </li> <li> Compliant with AEC‑Q100[9] Grade 0 </li> <li> Compliant with ASIL‑B[10] </li> </ul><table> <tbody><tr> <td rowspan="1" colspan="1"> Notes: </td> </tr> <tr> <td rowspan="1" colspan="1"> [6] Built-in ECC (Error Correction Code) function supports 1-bit error correction (SEC) and 2-bit error detection (DED). </td> </tr> <tr> <td rowspan="1" colspan="1"> [7] Programmable motor driver (PMD): A hardware module designed for motor-control that performs PWM (Pulse Width Modulation) generation, current conduction control, and fault detection in hardware, thereby reducing the processing load required for motor-control. </td> </tr> <tr> <td rowspan="1" colspan="1"> [8] 1-shunt resistor current sense amplifier: The motor current is indirectly estimated using a current-sensing shunt resistor and a current-sense amplifier. </td> </tr> <tr> <td rowspan="1" colspan="1"> [9] AEC-Q100: An automotive electronics qualification standard established by the Automotive Electronics Council, covering the reliability and quality of automotive electronic components, particularly integrated circuits (ICs). </td> </tr> <tr> <td rowspan="1" colspan="1"> [10] ASIL (Automotive Safety Integrity Level): An index indicating the automotive functional safety level based on the ISO 26262 functional safety standard.
