The highly integrated RAA271082 PMIC complements Rexa‘s award-winning AHL technology, and its strong flexibility enables it to support MCU for safety related applications
Renesa Electronics (TSE: 6723), a global semiconductor solution provider, today announced the launch of RAA271082, an innovative vehicle scale power management IC (PMIC) for the next generation of car camera applications. As a multi-functional and multi output power IC conforming to ISO-26262 standard, RAA271082 includes a primary high-voltage synchronous step-down regulator, two secondary low-voltage synchronous step-down regulators and a low-voltage LDO regulator, and provides four over-voltage and undervoltage (OV/UV) monitors, I2C communication, a configurable universal I/O pin, and a dedicated reset output/fault indication. To meet the strict ASIL B standard, RAA271082 has a second independent reference for OV/UV monitors, built-in power on self-test, independent OV/UV monitors, and continuous CRC error check for internal registers and I2C communication.
The highly integrated RAA271082 provides a universal power solution for car cameras. It is the ideal combination of Renesa‘s High Definition Link (AHL) technology. AHL enables car manufacturers to provide high-definition video using low-cost cables and connectors. This new PMIC simplifies the power supply design for car camera modules that need to meet functional safety standards, and can be used for cameras including look around/satellite, rear view, driver monitor and electronic rear-view mirror applications. It supports the power requirements of almost all image sensors, image signal processors (ISPs) and encoder technology combinations, as well as direct battery power supply and coaxial cable power supply.
In addition to the image system, RAA271082‘s high integration and comprehensive safety features make it an excellent power supply solution for 16 bit and 32 bit vehicle MCU in various vehicle applications.
Niall Lyne, Vice President of Renesa‘s Automotive Analog Power Supply and Video Business Unit, said: "The camera has become an indispensable configuration for all new models. Renesa‘s new PMIC is applicable to almost all car camera modules, which can provide all the features and functions required by users for power supply. It is also an excellent combination of AHL solutions that we have recently been rated as one of the ‘most innovative applications of computer vision technology‘."
Key features of RAA271082 PMIC
• Development process research and development based on ISO-26,262 standard, supporting the system functional safety objectives required by ASIL B
• Highly programmable support for all types of on-board image sensors from all major suppliers
• Each switching regulator provides 1A output current capacity to support the growing power demand of the latest generation of high-resolution vehicle image sensors
• Support universal on-board MCU with integrated reset generation, watchdog timer, and programmable GPIO
• Integrate multiple components and functions to reduce overall power consumption
Successful product portfolio with RAA271082 and AHL technology
To help users design a car camera system that uses both RAA271082 and AHL, Renesa launched a "successful product portfolio": AHL full digital dashboard solution. Rexa‘s "successful product portfolio" is based on components that are compatible with each other and can work seamlessly. It has a system architecture with technical validation, which brings optimized low-risk design to accelerate the speed of product launch. Reza has launched more than 300 "successful product combinations" based on various products in its product portfolio.
