S6BP401AW0SN1B000

Overview

The S6BP401AW0SN1B000 is a specialized automotive power management IC designed for Advanced Driver-Assistance Systems (ADAS). It integrates four synchronous step-down (buck) DC/DC converters and two low-dropout (LDO) linear regulators, providing six independent output channels. The device operates within an input voltage range of 2V to 5.5V and supports switching frequencies up to 2.1MHz. Packaged in a 40-pin QFN (6x6mm) format, it meets AEC-Q100 automotive quality standards and functions reliably across temperatures from -40°C to +85°C.

Feature Summary

Procurement Notes

Verify the specific suffix 'W0' against official Infineon documentation to confirm pin compatibility and electrical characteristics. Ensure the component meets current AEC-Q100 qualification requirements for your target automotive application. Cross-reference the 40-QFN package dimensions with your PCB layout guidelines before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring multiple regulated outputs from a single PMIC solution. It is suitable for applications needing both high-current switching regulation and precise analog supply voltages. Consider the 40-QFN package size constraints and thermal dissipation capabilities during the initial hardware design phase.
