The RAA271082 is a versatile 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.
It 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 stringent 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.
The highly integrated RAA271082 provides a universal power solution for automotive cameras. It is a suitable companion for Renesas’ Automotive High-Definition Link (AHL) technology that enables car manufacturers to deliver high-definition video using low-cost cables and connectors.
The PMIC simplifies power supply design for automotive camera applications requiring functional safety compliance, modules that include surround view/satellite, rearview, driver monitor, and e-mirror. It also 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.
In addition to imaging systems, the RAA271082’s high integration and comprehensive safety features make it a solution for 16- and 32-bit automotive MCUs in a variety of applications.
