RAA271082A4HNP#HA0

Overview

The RAA271082A4HNP#HA0 is an automotive-grade PMIC compliant with ISO-26262 ASIL-B standards. It integrates a primary high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and one LDO regulator. The device supports an input voltage range of 4V to 42V. Switching frequency is 2.2MHz. Output 1 provides 2.8V to 5.05V at 1A. Outputs 2 and 3 provide 0.85V to 3.3V at 1A each. It features four OV/UV monitors, I2C communication, and a configurable GPIO. Package is 24-TFQFN.

Feature Summary

ISO-26262 ASIL-B compliance with independent reference for overvoltage and undervoltage monitoring
Integrated topology including primary high-voltage and secondary low-voltage synchronous buck regulators alongside an LDO
Built-in self-test functionality at power-up and continuous CRC error checking on internal registers

Applications

Next-generation automotive camera applications
Adaptive multi-rail power systems in vehicles
High-definition camera power management

Procurement Notes

Verify the specific suffix #HA0 against official Renesas documentation to confirm OTP programming and OEM-specific options like Valeo VW AR HUD. Confirm AEC-Q100 Grade -1 qualification status and moisture sensitivity level (MSL 3) requirements during storage and handling. Ensure I2C interface compatibility with target microcontrollers.

Selection Notes

Select this component for applications requiring ASIL-B certified power management with integrated buck and LDO outputs. Consider the 24-SCQFN package size and surface-mount installation type. Evaluate the need for firmware options or specific customer part numbers if integrating with BYD RH850/P1x-C or similar processors.

Part Context

The RAA271082 series serves as a versatile power management solution for automotive environments. This specific variant belongs to the RAA271082 family, designed to reduce component count in complex vehicle architectures. It complements other Renesas automotive ICs by providing robust, safety-compliant power regulation for sensitive peripherals.
