Renesas release Automotive ASIL B PMIC RAA271082

Nov 08 2022

Renesas has released an innovative automotive-grade power management IC for next-generation automotive camera applications.

As the electrification and intelligence of automobiles become the trend, the market demand for functions is becoming more and more diverse. Among them, in-vehicle cameras have a wide range of applications, including driver assistance, vehicle surround view, vehicle occupant monitoring, etc., and are essential visual perception sensors for intelligent driving and intelligent cockpits.

Renesas PMIC RAA271082 for Automotive Camera Applications

The RAA271082 is a new PMIC from Renesas that creates a universal power supply solution for in-vehicle cameras and is an ideal match for Renesas' Automotive High-Definition Link (AHL) technology. AHL enables automakers to deliver high-definition video using low-cost cables and connectors.

Based on the ISO-26262 standard, the RAA271082 contains a primary high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and a low-voltage LDO regulator. It also provides four over-voltage and under-voltage (OV/UV) monitors, I2C communication, a configurable general-purpose I/O pin, a dedicated reset output, and a fault indication.

This PMIC features a second independent reference for OV/UV monitor, built-in power-on self-test, independent OV/UV monitor, and continuous CRC error checking for internal registers and I2C communication. Fully meets stringent ASIL B standards.

RAA271082 PMIC for Automotive Camera Applications

The highly integrated RAA271082 can simplify the power supply design of the vehicle camera module. Its high degree of programmability enables it to support the power requirements of nearly any combination of an image sensor, image signal processor (ISP), and encoder technology, as well as direct battery power as well as coax power.

Niall Lyne, vice president of the Automotive Analog Power and Video Business Unit at Renesas Electronics, said“Cameras are now an indispensable feature for all new vehicles. Our new PMIC delivers all the functionality our customers need in a compact form factor suitable for almost all automotive camera modules. It is an excellent companion for our AHL solution, recently named as one of the most innovative applications of computer vision technology.”

The RAA271082 can be used in cameras including surround view/micro, rear view, driver monitor, and electronic mirror applications. Supports general-purpose automotive MCUs (16-bit and 32-bit) with integrated reset generation, watchdog timer, and programmable GPIO.
