Toshiba Unveils Two '5A 2-Channel' H-Bridge Motor Drivers
Published2020.12.12 15:45Toshiba 5A H-bridge Motor Driver (2 Types)
Motor control via SPI communication, reducing MCU ports
As the number of H-bridge motor drivers used in automotive valves increases, there is a growing demand for system miniaturization and cost reduction. With the mandatory implementation of 'OBD II (On-Board Diagnostic II),' a requirement for second-generation on-board self-diagnostic equipment, in 2022, automotive motor driver ICs must be equipped with SPI communication capabilities.
On the 11th, Toshiba released two brushed DC motor driver ICs suitable for automotive applications, including electronic throttles. The wettable flank VQFN package 'TB9054FTG' will begin sampling this month and enter mass production in March 2022, while the power QFN package 'TB9053FTG' is scheduled to begin sampling in February 2021 and enter mass production in May 2022.
The TB9054FTG and TB9053FTG feature 5A 2-channel output drivers, which help reduce mounting area. A 10A 1-channel drive is also possible in parallel mode. Both products connect in a daisy-chained configuration and offer the ability to control motors solely via SPI communication, allowing for a reduction in the number of MCU ports. Additionally, with a size of 6.0mm × 6.0mm, they contribute to system miniaturization.

Bycor Supports Design of "Modular PDN" for 48V Electric Vehicle Battery Packs
BTCC allows drivers to tactically use electric motors to enhance vehicle performance and acceleration. In response, Delta Motorsports has designed a new battery pack and associated electronics for tactical boost functionality. The new 48V lithium-ion battery pack features innovative intelligent power management, high-power high-density DC-DC converters, and regulation systems. The battery pack supplies power to the inverter-motor combination while accommodating the power generated from this combination, and the high-power high-density converter solution supplies power to all electronic circuits and devices in the vehicle. The power density and power management achieved with this architecture enable control of the alternator system, further improving weight, performance, and reliability.

A single misaligned light means 'defect'… Vehicle interior lighting now guarded by semiconductors and software
Automotive interior lighting is moving beyond its role as 'auxiliary lighting.' As it becomes a core element of user experience (UX) that expresses brand identity through color and animation while reflecting driver preferences, the LED interior ambient lighting market is growing rapidly. In connection with this, we met in advance with Choi Young-jae, Research Director at Dabo Corporation, who will present a technical webinar session on "Intelligent LED Interior Lighting Solutions Illuminating Future Vehicles," to hear about market trends and changes in design requirements.
