MC33FS6528NAER2

Power Management - Specialized Overview

The MC33FS6528NAER2 is a System Basis Chip (SBC) from the NXP FS6500 series, designed for automotive power management. It integrates an SMPS-based DC/DC converter capable of delivering 2.2 A to the Vcore rail, alongside linear regulators and system monitoring features. The device operates within an input voltage range of 2.7 V to 40 V and supports output voltages from 1 V to 5 V. It functions reliably across an ambient temperature range of -40°C to +125°C. The component is housed in a 48-pin HLQFP package with exposed pad, facilitating surface-mount installation for robust thermal performance.

Power Management - Specialized Procurement Notes

Verify the complete part number including the trailing suffix against official NXP documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process. Ensure compatibility with existing PCB footprint designs for the 48-HLQFP package.

Power Management - Specialized Selection Notes

Select this component when a single-chip solution is required to manage both high-power core rails and auxiliary supplies in automotive environments. The integrated diagnostic capabilities via SPI simplify system monitoring compared to discrete regulator solutions. Consider the thermal dissipation requirements of the 2.2 A output when designing the PCB layout for the exposed pad.

Power Management - Specialized Part Context

This part belongs to the FS6500 family of System Basis Chips, which are tailored for automotive applications requiring high reliability and integrated power management. The FS6500 series consolidates multiple power stages and monitoring functions into a single package, reducing board space and component count for complex automotive electronic architectures.

Power Management - Specialized Replacement Considerations

The MC33FS6522NAER2 and MC33FS6523NAER2 are related variants within the same FS6500 family. Verify specific pinout compatibility and functional differences between these models before substitution, as internal regulator configurations may vary.
