Toshiba: TB9M001FTG, the second product in the Smart Motor Control Driver “SmartMCD™” series.
In recent years, as the electrification of automotive equipment has progressed, secondary devices[4] are increasingly required to offer higher performance, enhanced functionality, more compact designs, and fewer components. Toshiba has responded to these requirements, by developing the new product.
The new SmartMCD™ has four built-in low-side drivers that can be used for relay drivers and other applications, enabling forward and reverse control[5] of two brushed DC motors. It also features a built-in microcontroller (Arm® Cortex®-M0 core), high-capacity flash memory, two high-side drivers for power-supply applications, a LIN transceiver, and a power supply system that can operate at the automotive battery level. All of these functions are integrated into a compact VQFN48 package (7×7 mm typ.).
In addition to controlling brushed DC motors in automotive applications, such as power sunroofs, electric wipers, power windows, and power seats, the driver is also capable of controlling various sensors and actuators. Furthermore, through LIN control from the main ECU, it can be utilized as a secondary device for a wide range of applications. This enables efficient control of various automotive functions and supports a broad spectrum of automotive applications.
Toshiba will continue to expand its lineup of SmartMCD™ series and will contribute to downsizing of automotive systems and reducing the number of components used.
Notes:
[1] SmartMCD™: A series of ICs developed by Toshiba Electronic Devices & Storage Corporation that integrate motor control functions and a microcontroller.
