MC33FS4500NAE

Power Management - Specialized Overview

The MC33FS4500NAE is a System Basis Chip (SBC) from the NXP FS4500 series, designed for automotive applications. It integrates a linear 0.5A voltage regulator for the MCU core and supports input voltages up to 36V. The device operates within an ambient temperature range of -40°C to 125°C and is housed in a 48-pin HLQFP package with exposed pad. It complies with AEC-Q100 Grade 1 standards.

Power Management - Specialized Feature Summary

• Integrates highly flexible SMPS pre-regulator supporting non-inverting buck-boost and standard buck topologies
• Includes advanced functional safety features suitable for ASIL B or D applications
• Provides battery voltage sensing and MUX output pin capabilities
• Supports low-power modes with multiple wake-up sources including CAN, LIN, I/O, and Long Duration Timer

Power Management - Specialized Applications

• Powering microcontrollers in automotive systems
• Energy optimization via DC/DC pre-regulators and linear regulators
• ASIL B/D ready system basis chip implementations

Power Management - Specialized Procurement Notes

Verify the specific suffix 'NAE' against the official datasheet to confirm package type and temperature grade. Ensure compatibility with ASIL B/D requirements if safety integrity is critical. Confirm supply chain stability through NXP's long-term supply program documentation before finalizing procurement decisions.

Power Management - Specialized Selection Notes

Select this component when a linear 0.5A Vcore regulator is sufficient for the MCU power budget. Choose over switching variants if electromagnetic interference reduction is prioritized over efficiency. Verify that the 36V maximum input voltage aligns with the vehicle's electrical architecture specifications.

Power Management - Specialized Part Context

Part of the FS4500 family of professional PMICs. This specific model represents the Grade 1 automotive variant, differing from Grade 0 models which support higher junction temperatures. It serves as a central power management unit integrating communication interfaces and regulation.

Power Management - Specialized Replacement Considerations

Check for other FS4500 variants such as MC33FS4500LAER2 for reel packaging options. Compare with MC35FS4500xxx series for Grade 0 high-temperature requirements. Ensure substitute parts maintain identical pinout and regulatory compliance.
