Renesas Electronics Corporation, a provider of advanced semiconductor solutions, announced a new automotive Intelligent Power Device (IPD) that will securely and flexibly control power distribution within vehicles – meeting the requirements of E/E (electrical/electronic) architectures. next generation.
The new RAJ2810024H12HPD is available in the TO-252-7 small package and reduces the mounting area by about 40% compared to the conventional TO-263 package product.
Furthermore, the new device's advanced current detection function enables highly accurate detection of abnormal currents such as overcurrent. Because the new IPD detects abnormal currents even at low loads, it allows engineers to design highly safe and accurate power control systems capable of detecting even the smallest abnormalities.
“We are very pleased to launch a new generation of automotive IPDs with our new power MOSFET process,” said Akira Omichi, vice president of Renesas' automotive analog applications specific business division. “Renesas will continue to develop IPDs that improve the security 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 meet growing requirements as E/E architectures continue to evolve. In a conventional distributed E/E architecture, the battery power supply 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 lifespan 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 the ideal choice for building efficient and flexible power supply networks as they utilize shorter, longer wires. thin. The Renesas IPD, in particular, provides a more efficient, safer and smaller solution for power distribution control.
IPD Features:
- Single Channel High Channel IPD
- Small Package TO-252-7 (6.10 x 6.50 mm: excluding pins)
- Low resistance (Ron) of 2.3mΩ at 25°C (typ.)
- Highly accurate current detection at low loads
- Integrated charge pump
- Self-diagnosis feedback by load current detection
- Protection functions such as load short circuit, overheat detection, current output detection and open GND protection
- Supports 3.3V/5V logic interface
- Low standby current
- Battery reverse connection protection with automatic activation
- Compliant with AEC-Q100 and RoHS automotive standards
Renesas also offers the Electronic Fuse Power Distribution Box solution using an existing IPD. By replacing conventional fuses in the power supply box with small IPDs and programming the fuse characteristics into the microcontroller, developers can optimize the wiring harness and improve reliability through current monitoring.
This solution is part of Renesas' Winning Combinations, which optimally combines mutually compatible Renesas devices that work together seamlessly to reduce user design risk and shorten time to market.
