MC33FS4505KAER2

Power Management - Specialized Overview

The MC33FS4505KAER2 is a System Basis Chip (SBC) from the NXP FS4500 series, designed for automotive power management. It integrates a linear voltage regulator providing up to 0.5 A for the MCU core, alongside integrated CAN and LIN physical interfaces. 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 is housed in a 48-LQFP package with exposed pad and functions reliably across a temperature range of -40°C to +125°C.

Power Management - Specialized Feature Summary

Power Management - Specialized Procurement Notes

Verify the specific suffix 'K' against official NXP documentation to confirm it denotes Grade 1 automotive qualification and associated thermal ratings. Ensure the LQFP-48EP package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's current certification documents before finalizing procurement specifications.

Power Management - Specialized Selection Notes

Select this component when a single-chip solution combining power regulation and dual bus interfaces is required. It is suitable for applications needing isolated or tracked auxiliary supplies. Consider the 0.5 A linear regulator limit for core current demands. Evaluate if the integrated safety mechanisms reduce software complexity compared to discrete solutions.

Power Management - Specialized Part Context

This part belongs to the FS4500 family of System Basis Chips, which integrate PMIC functions with microcontroller support peripherals. The FS4500 series is engineered to optimize energy consumption through low-power modes and flexible pre-regulator topologies. It serves as a central hub for power distribution and communication in modern automotive electronic architectures.

Power Management - Specialized Replacement Considerations

Check NXP datasheets for cross-reference options within the FS4500 family, such as variants with DC/DC pre-regulators or different interface combinations. Verify pin compatibility and thermal performance characteristics before substituting with other SBC models.
