Toshiba: Toshiba Electronic Devices and Storage Corporation (Toshiba) has started providing engineering samples of the 'TB9104FTG', a gate driver designed for bridge circuits used in high-current automotive brushed DC motors. The company states that this product is tailored for body system applications such as power back doors, power sliding doors, and power seats.

According to BERNAMA News Agency, the rise in electrification of movable vehicle components has boosted the number of motors installed in automobiles, leading to a growing demand for more compact driver systems and lighter wiring harnesses. The TB9104FTG is housed in a small VQFN32 package with an exposed thermal pad, enhancing heat dissipation. When combined with external MOSFETs, it facilitates the creation of compact drive circuits for high-current brushed DC motors.

The device is equipped with a serial peripheral interface (SPI) for microcontroller connection, allowing the sharing of the SPI bus by multiple gate drivers, thereby reducing wiring complexity. It also incorporates a built-in Pulse Width Modulation (PWM) drive circuit, which supports continuous motor operation with a single rotation command, lessening the microcontroller's load and easing congestion on the SPI bus.

The TB9104FTG includes safety features such as a high-precision current sense amplifier for monitoring motor drive current, and it provides abnormality detection and drive-stop functions. Toshiba, a leading supplier of advanced semiconductor and storage solutions, aims to expand its range of driver ICs for automotive motors, contributing to the electrification and enhanced safety of vehicle systems.
