Toshiba Electronics Europe has begun commercial sample shipments of its gate-driver IC, the TB9084FTG, designed for controlling three-phase brushless dc (BLDC) motors.
BLDC motors are widely used across modern automotive platforms, including electric vehicles, where they support functions such as battery cooling pumps, thermal management fans, HVAC blowers, and body systems like power sliding doors, liftgates, and power seats.
As vehicle architectures continue shifting toward electrified systems, BLDC motors are increasingly replacing traditional brushed motors due to their efficiency, reduced noise, and longer operating life.
The TB9084FTG supports this transition by integrating the core functions required to drive three-phase BLDC motors, building on the architecture of the existing TB9083FTG.
The device incorporates a built-in charge pump, a motor current sense amplifier, an oscillation circuit, an SPI communication interface, and multiple abnormality detection circuits. These integrated functions contribute to component consolidation and support more compact system designs.
The IC is offered in a 6×6 mm VQFN36 package with a reduced pin count, achieved through an optimized circuit layout and a smaller chip footprint.
The TB9084FTG meets AEC-Q100 Grade 0 requirements and operates within an ambient temperature range from –40° to +150° C. The package also includes a wettable flank structure to facilitate optical inspection of solder joints during manufacturing.
Toshiba continues to evaluate automotive requirements as vehicles adopt more electrically driven subsystems and will expand its portfolio of gate driver ICs accordingly.
