A extremely built-in PMIC for next-generation automotive cameras, the Renesas RAA271082 is an ISO 26262-compliant multi-rail IC that meets stringent ASIL B metrics. The half employs a major high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and a low-voltage LDO regulator.
As well as, the RAA271082 packs 4 overvoltage and undervoltage (OV/UV) screens, a configurable GPIO pin, and a devoted reset output/fault indicator. To adjust to ASIL B necessities, the RAA271082 features a second unbiased reference for OV/UV monitoring, built-in self-test at power-up, unbiased OV/UV monitoring, and steady CRC error checking on inner registers and I2C communications.
A excessive diploma of programmability and 1 A of output present per switching regulator permits the RAA271082 to help all kinds of automotive picture sensors, in addition to 16-bit and 32-bit automotive MCUs in numerous of functions.
The RAA271082 is AEC-Q100 certified to Grade 1 and is available in a 4×4-mm, 24-lead step-cut QFN bundle with an uncovered pad for improved thermal efficiency. The PMIC is accessible right now, together with the RTKA271082DE0000BU analysis board.
