Toshiba Electronics Europe has begun shipping commercial samples of its latest gate driver integrated circuit (IC), the TB9084FTG, designed for three-phase brushless DC (BLDC) motors used in Automotive applications.

BLDC motors are increasingly replacing traditional brushed DC motors in vehicles due to their efficiency, durability, and quieter operation. They power a wide range of on-board systems, including sliding doors, tAIlgates, power seats, electric pumps, fans, and motor generators. This shift reflects the automotive industry’s broader move towards electrification, aimed at improving performance and user experience.

Building on the architecture of the TB9083FTG, the new TB9084FTG integrates key functions for three-phase motor control. These include a built-in charge pump circuit, a single-channel motor current sense amplifier, an oscillation circuit, SPI communication interface, and multiple abnormality detection circuits.

The IC’s compact design supports equipment miniaturisation, featuring a 6 x 6 mm VQFN36 package with fewer pins than its predecessor. This reduction was achieved through an optimised circuit layout and smaller chip size.

The TB9084FTG meets AEC-Q100 Grade 0 reliability standards, ensuring robust performance in extreme conditions with an operating temperature range from -40°C to +150°C. To improve assembly quality, the package incorporates a wettable flank structure, enabling easier visual inspection of solder joints.
