The TB9084FTG integrates essential functions for three-phase brushless motor drive, including a built-in charge pump circuit, a one-channel motor current sense amplifier, an oscillation circuit, an SPI communication circuit, and various sophisticated abnormality detection circuits.
The gate driver IC plays a crucial role in equipment miniaturisation. Its streamlined core functions enable the use of a compact 6 x 6mm VQFN36 package with a reduced pin count compared to TB9083FTG. This smaller package was made possible by a reduced chip size, achieved through an optimised circuit architecture.
The TB9084FTG also boasts exceptional robustness and quality, adhering to the rigorous AEC-Q100 Grade 0 reliability testing standards, with an operating ambient temperature range spanning from -40°C to +150°C.
Enhancing mounting reliability, the package incorporates a wettable flank structure, which simplifies visual inspection to confirm the integrity of soldered joints.
