S6BP401A90SN1B000

Overview

The S6BP401A90SN1B000 is an automotive-grade Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies. It integrates six output channels configured as four synchronous buck converters and two low-dropout linear regulators (LDOs). The device operates within a supply voltage range of 2.97V to 5.5V and supports a switching frequency of 2.1MHz. It is housed in a 40-QFN (6x6mm) package with exposed pad, designed for surface mount installation. The component is qualified to AEC-Q100 standards and functions reliably across a temperature range of -40°C to 125°C.

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm exact pin configuration and thermal characteristics. Ensure that the procurement channel provides valid traceability documents. Confirm compliance with RoHS3 requirements and check for any recent product change notices regarding manufacturing sites or material composition updates prior to finalizing orders.

Selection Notes

Select this component when a single IC solution is required to generate multiple distinct voltage rails for mixed-signal automotive loads. The combination of switching and linear regulation allows for efficient power conversion alongside noise-sensitive analog circuitry support. Evaluate the total output current capabilities against the system's peak load requirements to ensure adequate thermal performance within the specified operating temperature range.

Part Context

This part belongs to the S6BP401 series of automotive PMICs from Infineon Technologies. These devices are engineered specifically for high-reliability vehicle applications where stable power delivery is critical. The series typically includes variants with different output configurations or packaging options to suit diverse board designs while maintaining consistent automotive quality standards and interface compatibility.

Replacement Considerations

Direct substitutes include other S6BP401 family members such as S6BP401AJ1SN1B000, provided the electrical specifications and pinout remain compatible. Verify that alternative parts meet the same AEC-Q100 automotive grade requirements and operate within the identical voltage and temperature ranges before implementation.
