By Toshiba Electronic Devices & Storage Corporation has begun sample shipments of its new gate driver IC, the TB9103FTG, designed for automotive brushed DC motors. This innovative component is set to revolutionize the automotive industry by contributing to the downsizing of equipment, enhancing efficiency, and reducing costs. The TB9103FTG is specifically engineered to drive latch motors, lock motors, and other brushed DC motors used in power backdoors, power slide doors, power windows, and power seats. This development marks a significant step forward in Toshiba’s commitment to advancing automotive technology.
Enhancing Efficiency and Downsizing Equipment
The TB9103FTG gate driver IC is designed to streamline the functions and performance of brushed DC motors, which do not require speed control. This makes it ideal for applications where simple, reliable motor operation is essential. The IC features a built-in charge pump circuit that ensures the voltage needed to power external MOSFETs for driving motors. Additionally, it includes a gate monitoring function that prevents the generation of through-current by automatically controlling the output timing of the gate signal to the high-side and low-side external MOSFETs.
One of the key advantages of the TB9103FTG is its contribution to equipment downsizing. The IC is housed in a compact 4.0mm×4.0mm package, making it suitable for integration into smaller, more efficient automotive systems. This downsizing capability is particularly important as the number of electric motors integrated into vehicles continues to increase. By reducing the size and complexity of motor drivers, Toshiba’s new IC helps manufacturers create more compact and lightweight automotive components.
The TB9103FTG can operate as a gate driver for one-channel H-bridge or two-channel half-bridges, providing flexibility in its application. This versatility allows it to be used in a wide range of automotive systems, from power windows and seats to more complex applications like power backdoors and slide doors. The IC’s low-power standby mode with a built-in sleep function further enhances its efficiency, making it an attractive option for modern automotive designs.
Applications and Benefits
The TB9103FTG gate driver IC is designed to meet the specific needs of automotive applications. It is particularly well-suited for driving latch motors and lock motors in power backdoors and power slide doors, as well as drive motors for power windows and power seats. These applications require reliable and efficient motor operation, and Toshiba’s new IC delivers on both fronts.
In addition to its primary function as a motor driver, the TB9103FTG can also be combined with an external MOSFET to replace mechanical relays and other mechanical switches. This capability contributes to quieter operation and higher equipment reliability, as it eliminates the mechanical wear and tear associated with traditional switches. The IC’s ability to replace mechanical components with electronic solutions aligns with the broader industry trend towards increased electrification and automation in automotive systems.
The TB9103FTG’s streamlined design and advanced features offer several benefits to automotive manufacturers. By reducing the size and complexity of motor drivers, the IC helps manufacturers achieve greater design flexibility and efficiency. This, in turn, can lead to cost savings and improved performance in automotive systems. The IC’s low-power standby mode and built-in sleep function also contribute to energy efficiency, making it an environmentally friendly choice for modern vehicles.
Future Prospects and Industry Impact
The introduction of the TB9103FTG gate driver IC represents a significant advancement in automotive technology. As the automotive industry continues to evolve, the demand for efficient, reliable, and compact motor drivers is expected to grow. Toshiba’s new IC is well-positioned to meet this demand, offering a versatile and high-performance solution for a wide range of automotive applications.
Looking ahead, the TB9103FTG is likely to play a key role in the development of next-generation automotive systems. Its ability to support downsizing and enhance efficiency aligns with the industry’s focus on creating more sustainable and cost-effective vehicles. As manufacturers continue to integrate more electric motors into their designs, the need for advanced motor drivers like the TB9103FTG will only increase.
Toshiba’s commitment to innovation and quality is evident in the development of the TB9103FTG. By providing a reliable and efficient solution for driving brushed DC motors, Toshiba is helping to shape the future of the automotive industry. The company’s focus on downsizing and efficiency reflects broader industry trends and positions Toshiba as a leader in automotive technology.
