Renesas Electronics (TSE: 6723), a global semiconductor solutions provider, today announced the launch of the RAA271082, an innovative automotive-grade power management IC (PMIC) for next-generation in-car camera applications. as an ISO-26262-compliant multi-function multi-output power supply IC, the The RAA271082 includes a primary high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and a low-voltage LDO regulator, and provides four overvoltage and undervoltage (OV/UV) monitors, I2C communication, a configurable general-purpose I/O pin, and a dedicated reset output/fault indication. To meet stringent ASIL B standards, the RAA271082 features a second independent reference for the OV/UV monitors, built-in power-up self-test, independent OV/UV monitors, and continuous CRC error checking for internal registers and I2C communication.
The highly integrated RAA271082 creates a universal power solution for in-vehicle cameras. It is an ideal match for Renesas Automotive High Definition Link (AHL) technology, which enables automakers to deliver HD video with low-cost cables and connectors. This new PMIC simplifies power supply design for in-vehicle camera modules that need to meet functional safety standards for cameras including surround view/satellite, rear view, driver monitor and electronic rear view mirror applications. It supports power requirements for virtually all combinations of image sensor, image signal processor (ISP) and encoder technologies, as well as direct battery power and coaxial cable power. In addition to imaging systems, the RAA271082's high level of integration and comprehensive safety features make it an excellent solution power solution for 16-bit and 32-bit automotive MCUs in a variety of in-vehicle applications.
Cameras are now an essential feature in all new models," said Niall Lyne, vice president of the Automotive Analog Power & Video Division at Renesas Electronics. Renesas' new PMICs are suitable for almost all in-vehicle camera modules and provide all the features and functionality users need to power them, and are an excellent match for our AHL solution, which was recently named one of the 'Most Innovative Applications in Computer Vision Technology'."
