RAA271082A4HNP#MA0 is an automotive PMIC with three synchronous buck regulators and one low dropout linear regulator. It is a versatile multi-rail power IC comprised of a primary high voltage synchronous buck regulator, two secondary low voltage synchronous buck regulators, and an LDO regulator. It offers four overvoltage and undervoltage monitors, I²C communications, a general-purpose I/O pin, and a dedicated reset output/fault indicator. It was designed using an ASIL-D ISO-26262 development process and is intended to meet ASIL-B device metrics. It includes a second bandgap reference for the 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. Application includes driver monitoring cameras, rear and surround view HD automotive cameras, microcontroller PMIC for battery management systems, microcontroller PMIC for zone and domain controllers, microcontroller PMIC for gateway unit.
