S6BP401AY1SN1B000

Overview

The Infineon S6BP401AY1SN1B000 is a specialized automotive Power Management IC (PMIC) belonging to the S6BP401A series. It integrates six output channels, comprising four synchronous buck converters and two low-dropout regulators (LDOs). The device operates within an input voltage range of 2.97V to 5.5V and supports a switching frequency of 2.1MHz. Designed for high reliability, it features a 40-QFN (6x6mm) package with exposed pad and is qualified to AEC-Q100 standards for operation across an extended temperature range of -40°C to +125°C.

Feature Summary

• Integrates four synchronous buck converters and two LDOs in a single compact package
• Automotive-grade qualification ensuring reliability under harsh environmental conditions
• Supports flexible power rail configurations for complex system architectures

Applications

• Advanced Driver Assistance Systems (ADAS)
• Automotive infotainment systems
• Vehicle gateway controllers

Procurement Notes

Verify the specific suffix 'Y' against official Infineon documentation to confirm exact pinout or functional variations compared to standard variants. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm that the 40-QFN package aligns with assembly capabilities. Cross-reference the part number with current availability status to avoid obsolescence risks during production.

Selection Notes

Select this component when a highly integrated solution is required to minimize board space and component count. It is suitable for designs needing multiple regulated rails from a single variable input source. Consider the 2.1MHz switching frequency for inductor size optimization. Evaluate thermal performance due to the dense integration of six regulators in a small footprint.

Part Context

This PMIC is part of the S6BP401 family, designed specifically for automotive applications requiring robust power management. It replaces discrete power solutions by consolidating multiple regulator functions into one chip. The family is known for its high efficiency and compact form factor, making it ideal for space-constrained electronic control units in modern vehicles.
