RAA271082 Automotive PMIC with Three Synchronous Buck Regulators and One Low Dropout Linear Regulator Datasheet

PublishTime：2023-03-13

●The RAA271082 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. RAA271082 was designed using an ASIL-D ISO-26262 development process and is intended to meet ASIL-B device metrics. The RAA271082 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.
●Requiring few external components and minimal board space, the RAA271082 provides a high-density power solution. It offers an extensive feature set configured using internal One-Time Programmable (OTP) memory. Nearly all device options such as each output voltage selection, power sequencing, and OV/UV thresholds are internally configured and require no external components for selection. The regulators also offer internal compensation. The bucks are synchronous to achieve high efficiency and are capable of operating in harsh environments requiring high ambient temperature.
●The RAA271082 is available in a 4mm×4mm 24-lead Step Cut QFN (SCQFN) package with an exposed pad for improved thermal performance. It is AEC-Q100 qualified to Grade 1 and operates across an ambient temperature range of -40°C to 125°C and is electrically specified across a junction temperature range of -40°C to 150°C. Automotive PMIC for 32-bit Microcontrollers in BMS, Zone Controller, Domain Controller, and Gateway applications.
