Toshiba Electronic Devices & Storage Corporation has announced that its second-generation Smart Motor Control Driver IC, the TB9M001FTG, has begun sample shipments. This chip integrates a relay drive circuit, a microcontroller (based on the Arm® Cortex®-M0 core), and a LIN transceiver, enabling simultaneous relay driving and control of two DC brushed motors. It provides a highly integrated solution for automotive motor applications.

The new product adopts a compact VQFN48 package (7mm×7mm), integrating four low-side drivers, two high-side drivers, large-capacity flash memory, and an automotive battery-level power system into a single chip. This design significantly reduces the number of external components, contributing to more compact automotive electrical system designs.

The TB9M001FTG is suitable for controlling DC motors in automotive applications such as sunroofs, wipers, windows, and seats. It can communicate with the main ECU via the LIN bus, functioning as an auxiliary device to control various sensors and actuators. The launch of this chip further enriches Toshiba's product portfolio in the automotive motor drive sector, offering an efficient and integrated control solution for next-generation automotive electrification systems.
