Reza Electronics launched a new automotive intelligent power device

Reza Electronics (TSE: 6723), a global semiconductor solution provider, today announced the launch of a new automotive intelligent power device (IPD), which can safely and flexibly control the power distribution in the vehicle and meet the requirements of the new generation of E/E (electrical/electronic) architecture. The new RAJ2810024H12HPD uses a small TO-252-7 package, which reduces the installation area by about 40% compared with the traditional TO-263 package product. In addition, the advanced current detection function of the new device can realize high-precision detection of abnormal current such as overcurrent. Because the new IPD can detect abnormal current even at low load, it allows engineers to design a highly safe and accurate power control system, and even detect the smallest abnormal situation.

"We are very excited to launch the new generation of automobile IPD using the new power MOSFET technology of Ruisa," said Da Dao Zhao, vice president of the specific business department of Ruisa Electronic Automobile Simulation Application. Ruisa will continue to devote itself to the development of IPD, improve the safety and reliability of the power supply system, and build system-level solutions with our microcontrollers to promote the system development of users

With the continuous development of E/E architecture, the launch of the new IPD has met 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 a long and thick wire harness through the electrical box composed of mechanical relays and fuses. Compared with mechanical relays, IPDs have longer life and are maintenance-free, so they can be placed anywhere in the vehicle. With the evolution of the automobile industry to centralized or partitioned E/E architecture, IPD is becoming an ideal choice for building efficient and flexible power supply network due to its shorter and thinner wiring harness. Therefore, Reza's IPD device has created a more effective, safer and compact solution for power distribution control.

Key features of the new IPD (RAJ2810024H12HPD)

● Single-channel high-end IPD

● Small TO-252-7 package (6.10mm x 6.50mm: excluding pins)

● Low on-resistance (Ron) is 2.3m Ω (typical value) at 25 ° C

● High precision current detection under low load

● Built-in charge pump

● Self-diagnosis feedback of load current sensing

● Load short circuit, overheat detection, sensing current output, GND open circuit protection and other protection functions

● Support 3.3V/5V logic interface

● Low standby current

● Battery reverse connection protection with self-starting function

● Comply with AEC-Q100 and RoHS automobile standards

"Electronic fuse distribution box" solution

Based on the existing IPD devices, Ruisa launched the "electronic fuse distribution box" solution. The traditional fuse in the electric box is replaced by a small IPD, and the fuse characteristics are programmed into the microcontroller. Developers can optimize harnesses and improve reliability through current monitoring. This solution is part of the "successful product portfolio" of Renesa. Reza's "successful product portfolio" optimizes and combines compatible Reza devices to achieve seamless collaboration, so as to reduce user design risk and shorten time to market. Resa has launched more than 300 "successful product portfolios" based on various products in its product portfolio.

Supply information

RAJ2810024H12HPD can now provide samples and is planned to mass produce in the first quarter of 2024.
