Japanese semiconductor supplier Renesas has launched a new automotive power management IC for next-generation automotive camera applications. The RAA271082 supports the power requirements of almost any combination of image sensor, image signal processor (ISP) and encoder technology, while also supporting direct-from-battery as well as power-over coax supply.
The RAA271082 is designed to simplify power supply design for automotive camera applications requiring functional safety compliance, modules that include surround view/satellite, rearview, driver monitor, and e-mirror. It is an ISO-26262 compliant multi-rail power IC with a primary high voltage synchronous buck regulator, two secondary low voltage synchronous buck regulators, and a low voltage LDO regulator.
The new PMIC offers four overvoltage and undervoltage (OV/UV) monitors, I2C communications, a configurable general-purpose I/O pin, and a dedicated reset output/fault indicator. To meet ASIL B metrics, the RAA271082 includes a second independent reference for OV/UV monitors, built-in self-test at power-up, independent OV/UV monitoring, and continuous CRC error checking on internal registers and I2C communications.
“Cameras are now an indispensable feature for all new vehicles,” said Niall Lyne, Vice President of the Automotive Analog Power and Video Business Division at Renesas. “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.”
