RAA271082A4HNP#AA0

Overview

The RAA271082A4HNP#AA0 is an automotive-grade PMIC featuring a 4V to 42V input range. It integrates three synchronous buck regulators and one LDO, providing four non-isolated outputs with a switching frequency of 2.2MHz. The device supports AEC-Q100 Grade -1 qualification and operates from -55°C to 150°C TJ. Outputs include 1A channels at 2.8V-5.05V and 0.85V-3.3V ranges. Packaged in a 24-SCQFN (4x4mm) with wettable flanks.

Feature Summary

• ISO-26262 compliant ASIL-B architecture with independent reference for overvoltage/undervoltage monitors
• Integrated built-in self-test at power-up and continuous CRC error checking on internal registers
• Configurable general-purpose I/O pin with dedicated reset output and fault indicator
• I2C communication interface for system control and monitoring

Applications

• Next-generation automotive camera systems
• High-definition (HD) camera power management
• Automotive infotainment subsystems requiring multi-rail power
• ADAS sensor modules needing ASIL-B compliance

Procurement Notes

Verify the specific suffix AA0 against the manufacturer's official datasheet to confirm firmware options and OTP configurations. Ensure the ordering part number matches the required automotive grade and package variant. Cross-reference the latest PCN documents for any label or manufacturing site changes before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring ISO-26262 ASIL-B certified power management for automotive cameras. It is suitable for applications needing a wide input voltage range up to 42V and multiple regulated rails. Consider the 24-SCQFN package constraints and thermal requirements for high junction temperature operation up to 150°C.

Part Context

This part belongs to the RAA271082 family of four-channel ASIL-B PMICs designed specifically for automotive camera applications. It complements other Renesas automotive power solutions by offering integrated safety features alongside standard voltage regulation capabilities in a compact footprint optimized for space-constrained vehicle electronics.

Replacement Considerations

Consult official substitution lists for variants such as RAA271082A4HNP#HA0 which may differ in packaging or firmware options. Verify compatibility with existing board layouts and software drivers when considering alternative suffixes within the same product family.
