MC35FS6506NAE

Power Management - Specialized Overview

The MC35FS6506NAE is a Grade 0 Safety Power System Basis Chip from NXP Semiconductors, designed for automotive applications. It integrates a DC/DC converter with a 1.5 A Vcore output and an LDO, housed in an LQFP48EP package. 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 features a maximum operating temperature of +150 °C (ambient) and +175 °C (junction), complying with AEC-Q100 Grade 0 standards.

Power Management - Specialized Feature Summary

• Integrates a high-current 1.5 A DC/DC pre-regulator for efficient MCU core power supply
• Includes integrated CAN FD transceiver compliant with ISO 11898-2 and -5 standards
• Features advanced functional safety mechanisms including monitoring of critical analog parameters and a fail-safe state machine

Power Management - Specialized Applications

• Power Train systems
• ASIL B or D automotive applications
• MCU power management in high-temperature environments

Power Management - Specialized Procurement Notes

Verify the specific suffix 'NAE' against official documentation to confirm package type and tape/reel specifications. Ensure compatibility with AEC-Q100 Grade 0 requirements for high-temperature operation up to 150 °C ambient. Confirm that the 1.5 A DC/DC output current meets the target MCU's peak load demands during system initialization and active states.

Power Management - Specialized Selection Notes

Select this component when a Grade 0 qualification is required for extreme thermal environments. The 1.5 A DC/DC output provides higher efficiency than linear regulators for high-power MCUs. Verify that the LQFP48EP package fits the PCB layout constraints and that the integrated CAN FD interface matches the network topology requirements without needing external transceivers.

Power Management - Specialized Part Context

This part belongs to the FS6500 family of Safety Power System Basis Chips. It shares architectural similarities with other FS65xx variants but differs in output current capabilities and specific safety grade qualifications. The FS6500 series is designed to reduce software complexity by integrating power management and communication interfaces into a single chip.

Power Management - Specialized Replacement Considerations

Check the FS6500 family datasheet for pin-compatible alternatives such as the MC33FS6506NAER2, noting differences in packaging (Reel vs Tray) and potential minor parameter variations. Ensure any substitute maintains the Grade 0 automotive qualification and 1.5 A output capability.
