RAA271082 Automotive Power Management IC with Three Synchronous Buck Regulators and One Low Dropout Linear Regulator

PublishTime：2022-04-22

●The RAA271082 is a versatile ISO-26262 compliant 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. To meet stringent ASIL-B metrics, the RAA271082 includes a second independent 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.
●The RAA271082 is intended for high-density power applications, requiring few external components and minimal board space. 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.
●RAA721082 is available in a 4mmx4mm 24 Ld 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
