Power Device Released by Renesas Enables Safe Power Distribution in Next-Gen E/E Architectures

Written by Stephen Vicinanza

Power device released by Renesas enables safe power distribution in next-gen E/E architectures. The announcement came for an Intelligent Power Device (IPD) that the company is saying is a safe and flexible power distribution system in automotive vehicles.

The IPDs are addressing next-generation requirements for Electric/Electronic (E/E) architectures. The latest device is the RAJ2810024H12HPD and is available in a small TO-252-7 package. The compact size of the device reduces mounting areas by as much as 40% compared to the traditional TO-263 package product.

There is a new advanced current detection function that allows for greater accuracy when detecting abnormal currents, such as in the case of overcurrent. This IPD detects abnormal currents even in low-load scenarios, which allows engineers to design highly safe and precise power control systems. In this, the company feels it more readily detects small abnormalities.

“We are very pleased to launch a new generation of automotive IPDs featuring our new power MOSFET process,” said Akira Omichi, Vice President of Renesas’ Automotive Analog Application Specific Business Division. “Renesas will continue to develop IPDs that improve the safety and reliability of power supply systems and facilitate system development for our customers by offering system-level solutions with our microcontrollers.”

This new IPD was developed with the rapidly growing requirements for such industry standards as the E/E architecture, as they grow and evolve. The IPDs are maintenance-free and have a longer life than mechanical relays. The Electronic Control Units in a conventional distributed E/E architecture are hampered by wires and the need for a power box with mechanicals inside.

The automotive industry is rapidly moving towards a more centralized and zone-orientated E/E architecture, making IPDs more desirable when it comes to efficiency and flexibility. The shorter thinner wire system allows for this more flexible power supply network. The results are coming around to a more efficient, smaller, and overall safer solution to the common ECUs.

The availability of the RAJ2810024H12HPD is limited to sample quantities at this time. Mass production is slated for the first Quarter of 2024.
