MC33FS4507NAER2

Power Management - Specialized Overview

The MC33FS4507NAER2 is a System Basis Chip (SBC) from the NXP FS4500 series, designed for automotive power management. It integrates a linear voltage regulator providing 0.5 A to the MCU core, operating within an input voltage range of 2.7 V to 40 V and delivering adjustable output voltages between 1 V and 5 V. The device supports ASIL B or D safety applications and includes integrated CAN FD and LIN physical interfaces compliant with ISO 11898-2 and LIN 2.2 standards. Packaged in an LQFP-48EP, it operates across a temperature range of -40°C to +125°C.

Power Management - Specialized Procurement Notes

Verify the specific suffix 'R2' indicates tape-and-reel packaging when sourcing components. Confirm that the selected variant aligns with required automotive qualification levels and interface specifications. Ensure compatibility with existing PCB footprints for the LQFP-48EP package. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component when a linear regulator topology is preferred for the MCU core due to noise sensitivity requirements. The 0.5 A output current capacity suits microcontrollers with moderate power consumption. Consider the integrated communication interfaces if board space for separate transceivers is limited. Verify that the thermal performance meets system constraints given the linear regulation approach.

Power Management - Specialized Part Context

This part belongs to the NXP FS4500 family of System Basis Chips, which combine power management and communication interfaces. The FS4500 series targets automotive applications requiring high reliability and functional safety. Variants within the series differ by regulator type (linear vs. DC/DC) and output current capabilities, allowing customization for specific MCU power profiles.

Power Management - Specialized Replacement Considerations

Direct substitutes include other MC33FS450x variants within the FS4500 family, such as MC33FS4507NAE, differing primarily in packaging format. Alternative parts must match the 0.5 A linear regulator specification and LQFP-48EP footprint. Verify that any replacement maintains identical safety integrity levels and interface protocols.
