MC33FS4500LAER2

Power Management - Specialized Overview

The MC33FS4500LAER2 is a System Basis Chip (SBC) from NXP USA Inc., designed for automotive applications. It integrates power management and communication interfaces in a 48-HLQFP package. The device supports a supply voltage range of 1V to 5V and features a linear regulator with a maximum output current of 0.5A. It operates within a temperature range of -40°C to 125°C and meets AEC-Q100 Grade 1 standards.

Power Management - Specialized Feature Summary

• Integrates CAN FD and LIN physical interfaces compliant with ISO 11898-2, -5, and LIN 2.2/2.1/J2602-2 standards.
• Includes advanced functional safety mechanisms such as a fail-safe state machine and critical analog parameter monitoring.
• Supports low-power modes with multiple wake-up sources including CAN, LIN, I/O, and Long Duration Timer.

Power Management - Specialized Applications

• Automotive microcontroller unit (MCU) power supply and control
• Body control modules requiring ASIL B or D readiness
• Sensor interface circuits with dedicated linear regulators

Power Management - Specialized Procurement Notes

Verify the specific suffix LAER2 against the official NXP datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 48-HLQFP form factor. Confirm that the 0.5A linear regulator output meets system load requirements before finalizing procurement.

Power Management - Specialized Selection Notes

Select this component when an integrated solution combining MCU power, CAN FD, and LIN connectivity is required. It is suitable for designs needing ASIL B/D readiness without complex external circuitry. Consider the 0.5A LDO limit for core voltage if higher currents are needed, in which case other series variants may be appropriate.

Power Management - Specialized Part Context

This part belongs to the FS4500 family of System Basis Chips. It is specifically designated for Grade 1 automotive applications, operating up to 125°C ambient temperature. The LAER2 suffix indicates the specific tape-and-reel packaging configuration for surface-mount assembly.

Power Management - Specialized Replacement Considerations

Direct substitutes include other MC33FS4500 variants with different suffixes for package or temperature grades. Cross-reference with MC33FS4502LAER2 for similar functionality but verify pinout and current capabilities carefully.
