Toshiba launches second product in its SmartMCD series for automotive
Toshiba has started sample shipments for the TB9M001FTG, the second product in their Smart Motor Control Driver (SmartMCD) series. This highly integrated device is specifically designed to deliver efficient and accurate control of brushed DC motors in automotive applications, including electric sunroofs, wipers, powered windows, and adjustable seats.
The SmartMCD TB9M001FTG integrates four low-side drivers that function as relay drivers, enabling forward and reverse control of two brushed DC motors when using single-pole double-throw (SPDT) relays. In addition, the device features a built-in microcontroller (MCU) with an Arm Cortex-M0 core, 192kB of Flash memory and an additional 16kB of Data Flash. It also includes two high-side drivers for supporting 5V and 12V loads to external components, a LIN-transceiver for in-vehicle communication, and a fully integrated power management system that generates all the required voltage levels from the car battery. All these functions are integrated into a compact VQFN48 package, measuring just 7mm x 7mm (typ.), enabling engineers to realise more compact system designs and reduce component count.
The TB9M001FTG is AEC-Q100 (Grade 1) qualified and meets ASIL-A requirements. It includes robust safety features such as built-in error detections for overcurrent (low-side driver, high-side driver), over-voltage, under-voltage, and thermal shutdown protection.
