Renesas Electronics launches new automotive-grade smart power devices to enable safe, flexible power distribution in next-generation E/E architecture

On January 17, Renesas Electronics, a global supplier of semiconductor solutions, announced today the launch of a new automotive-grade intelligent power device (IPD) that can safely and flexibly control power distribution in vehicles to meet the needs of the new generation of E/E (Electrical/Electronic) Architecture Requirements. The new RAJ2810024H12HPD adopts a small TO-252-7 package, which reduces the mounting area by about 40% compared with traditional TO-263 package products. In addition, the new device's advanced current detection function enables high-precision detection of abnormal currents such as overcurrent. Because the new IPD can detect abnormal currents even at low loads, it allows engineers to design highly secure and precise power control systems that can detect even the smallest abnormalities.

Akira Daidai, vice president of the Automotive Analog Application Specific Business Unit at Renesas Electronics, said: "We are very excited to launch a new generation of automotive IPDs using Renesas' new power MOSFET process. Renesas will continue to be committed to the development of IPDs and improve the safety of power systems. performance and reliability, and work with our microcontrollers to build system-level solutions that drive user system development.”

With the continuous development of E/E architecture, the launch of new IPD meets the growing market demand. In the traditional distributed E/E architecture, the power from the battery is distributed to each electronic control unit (ECU) through an electrical box composed of mechanical relays and fuses, and through a long and thick wire harness. Compared to mechanical relays, IPDs have a longer life and are maintenance-free, allowing them to be placed anywhere on the vehicle. As the automotive industry evolves towards centralized or partitioned E/E architecture, IPD is becoming an ideal choice for building efficient and flexible power networks due to the use of shorter and thinner wire harnesses. Therefore, Renesas' IPD devices create a more effective, safer and smaller solution specifically for power distribution control.

"Electronic fuse distribution box" solution

Renesas launched the "electronic fuse distribution box" solution based on existing IPD devices. Use small IPDs to replace traditional fuses in electrical boxes and program the fuse characteristics into the microcontroller. Developers can optimize wiring harnesses and improve reliability through current monitoring. The solution is part of Renesas’ “successful product portfolio.” Renesas' Success Portfolio optimizes and combines compatible Renesas devices to work seamlessly together to reduce user design risks and shorten time to market. Renesas has now launched more than 300 "successful product portfolios" based on various products in its product lineup.

Samples of RAJ2810024H12HPD are available now, with mass production planned for the first quarter of 2024.
