• Automotive electronic control units requiring multi-rail regulation

Procurement Notes

Verify the specific suffix 'L2' against official Infineon documentation to confirm pin compatibility and functional equivalence with other S6BP401 variants. Confirm current production status as some listings indicate restricted availability or end-of-life transitions. Ensure the package type matches the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing automotive systems requiring a single-chip solution for multiple regulated rails. The integration of both switching and linear regulators allows for optimized efficiency and noise-sensitive load handling. Verify that the 40-QFN package dimensions fit the mechanical constraints of the application board.

Part Context

This part belongs to the S6BP401 family of automotive PMICs developed by Infineon Technologies. These devices are engineered specifically for the demanding environment of modern vehicles, offering compact integration to reduce board space. The family includes various output configurations tailored for different automotive subsystems.

Replacement Considerations

Consult official Infineon substitution guides for compatible alternatives. Direct replacements must match the 40-QFN package and maintain AEC-Q100 automotive qualification. Verify that any substitute provides equivalent output currents and voltage ranges.
