Toshiba outlines gate driver IC for BLDC motors
Toshiba has started commercial sample shipments of its TB9084FTG gate driver IC for three-phase BLDC motors, targeting automotive body electronics and auxiliary systems. The device builds on the company’s earlier TB9083FTG and is positioned for compact motor control designs. This may be interesting for eeNews Europe readers because BLDC-based actuators, pumps, and thermal systems continue to expand across vehicle platforms in Europe, and because gate-driver integration influences cost and board space in distributed architectures.
Device positioning and automotive context
According to Toshiba’s release, the TB9084FTG incorporates a charge pump, current-sense amplifier, SPI interface, oscillator, and several diagnostic circuits. These functions are aimed at supporting single-shunt current measurement and potentially reducing external component count in small motor control units. The IC is offered in a 6 × 6 mm VQFN36 package with a lower pin count than its predecessor, enabled by an optimised circuit architecture.
The company notes that BLDC adoption continues to grow as automakers replace brushed motors in body systems such as power doors, liftgates, seats, fans, and pumps. In European platforms, these actuators support comfort, ADAS-related cooling pumps, and thermal management subsystems, making gate-driver integration a relevant design topic for engineers.
Reliability and package features
The TB9084FTG meets AEC-Q100 Grade 0, supporting operation from –40 to +150 °C, which potentially addresses harsh-environment zones in EVs and hybrids. Toshiba highlights a wettable-flank package structure intended to simplify automated optical inspection and help ensure solder-joint quality.
Toshiba adds that it plans to continue expanding its gate-driver portfolio, monitoring market requirements and adjusting feature sets accordingly.
