Scalable 7-Channel 42V ASIL D Power Management IC for Automotive & Industrial MCUs

The RAA271084 Automotive Safety Integrity Level D (ASIL D) and RAA271084-B (ASIL B) are general-purpose Power Management Integrated Circuits (PMICs) with a high-voltage front-end, optimized for MCU power in automotive applications. They feature a high-voltage buck/boost controller, a low-voltage synchronous buck controller, and five linear regulators (LDOs), two of which can operate as trackers.

The RAA271084 supports ASIL D system safety goals, while the RAA271084-B supports ASIL B. Both include key safety features such as voltage monitoring, temperature monitors, watchdog timer, reset generator, and a safety-control state machine.

Available in 48-lead SCQFN and LQFP-EP packages (RAA271084) and SCQFN (RAA271084-B), both devices are AEC-Q100 Grade 1 qualified for -40°C to 125°C operation. These products are intended for ISO 26262-compliant applications, though safety analysis and assessment are ongoing and subject to change.
