Toshiba has begun supplying engineering samples of a gate driver IC TB9084FTG for three-phase brushless DC motors that drive essential onboard functions, including automotive body system applications, electric pumps and motor generators.
Many mechanically controlled parts of road vehicles are now electrified, and vehicles incorporate more than one electric motor, including those used in automotive body system applications. This transition has pushed the replacement of brushed DC motors with quieter and longer-lasting brushless DC motors.
TB9084FTG is designed to address this shift. It offers the minimum required gate driver IC functions for automotive applications, and supports a wide range of automotive motor applications in combination with external devices, such as MOSFETs, power supply ICs, microcontrollers and communication.
It is a flexible system, as any change in customer requirements can be supported by replacing corresponding external devices. Minimizing functions allows enables one of the industry’s smallest packages. The package also has a wettable flank structure, promoting visual inspection to confirm the reliability of soldered joints.
Toshiba will continue to expand its line-up of gate driver ICs by assessing market needs and optimizing product functions. It also plans to introduce new products that extend the electrification and improve the safety of automotive equipment.
