S6BP401AJ1SN1B000

Overview

The S6BP401AJ1SN1B000 is a six-output power management integrated circuit (PMIC) designed for automotive applications. It integrates four synchronous buck converters and two low-dropout linear regulators within a single package. The device operates with an input voltage range of 2.97V to 5.5V and supports a switching frequency of 2.1MHz. It is qualified to AEC-Q100 standards and functions reliably across a temperature range of -40°C to 125°C.

Feature Summary

• Integrates four synchronous buck converters and two LDOs for comprehensive power distribution
• Automotive-grade qualification ensuring reliability in harsh environments
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Advanced driver-assistance systems (ADAS)
• Automotive infotainment units
• Vehicle sensor modules

Procurement Notes

Verify the complete part number including suffixes to ensure correct package and tape-and-reel specifications. Confirm that the intended application meets the specified operating temperature and voltage requirements. Check for any specific quality certifications required by the end product. Ensure compatibility with the target PCB layout guidelines provided in the official documentation.

Selection Notes

Select this component when a compact, multi-rail solution is required for automotive electronics. The combination of switching and linear regulation allows for efficient power conversion alongside noise-sensitive analog supplies. Consider the total output current capabilities and thermal performance relative to the system's power budget and enclosure constraints.

Part Context

This PMIC belongs to the S6BP401 family, which provides integrated power management solutions for complex automotive electronic control units. The family is engineered to reduce bill-of-materials count and simplify board design by consolidating multiple regulator stages into a single chip.

Replacement Considerations

Check for updated suffix variations such as S6SBP401AM2SA100 which may indicate different packaging or evaluation configurations. Verify pin-to-pin compatibility before substituting with other members of the S6BP series.
