Semiconductor manufacturer Renesas Electronics has announced a new automotive Intelligent Power Device (IPD) that is designed to safely and flexibly control power distribution within vehicles, addressing the requirements of next-generation E/E (electrical/electronic) architectures. The RAJ2810024H12HPD is available in the small TO-252-7 package and reduces the mounting area by about 40% compared to the conventional TO-263 package product.
In addition, the advanced current detection function of the device allows highly accurate detection of abnormal currents such as overcurrent. Since the new IPD detects abnormal currents even at low loads, it allows engineers to design highly safe and precise power control systems that can detect even the smallest abnormalities.
“We are very pleased to launch a new generation of automotive IPDs featuring our new power MOSFET process,” says 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.”
The new IPD was developed to address the growing requirements as E/E architectures continue to evolve. In a conventional distributed E/E architecture, power supply from the battery is distributed to each Electronic Control Unit (ECU) via long, thick wires from a power box consisting of mechanical relays and fuses. IPDs have a longer life and are maintenance free compared to mechanical relays, so they can be placed anywhere in the vehicle.
As the automotive industry moves toward centralized or zone-oriented E/E architectures, IPDs are becoming an ideal choice for building efficient and flexible power supply networks since they use shorter, thinner wires. Its IPD in particular, says the company, provides a more efficient, safer and smaller solution for power distribution control.
Key Features of the RAJ2810024H12HPD) include:
- Self-diagnostic feedback by load current sense
- Protection functions such as load short-circuit, overheat detection, sense current output, and GND open protection
- Supports 3.3V/5V logic interface
- Low standby current
- Battery reverse connection protection with self-turn-on
- Compliant with AEC-Q100 and RoHS automotive standards
The RAJ2810024H12HPD is available now in sample quantities with mass production scheduled in Q1/2024.
