MC35FS6511NAE

Power Management - Specialized Overview

The MC35FS6511NAE is a Grade 0 automotive Power System Basis Chip (SBC) from the FS6500 series, designed for high-temperature environments with an ambient temperature rating of 150°C and junction temperature up to 175°C. It integrates a DC/DC pre-regulator capable of delivering 1.5A to MCU cores within a 1.0V to 5.0V range, alongside linear regulators for auxiliary and I/O supplies. The device supports CAN FD and LIN interfaces compliant with ISO 11898 and LIN standards. Operating voltage ranges from 2.7V to 40V, housed in an LQFP-48EP package.

Power Management - Specialized Feature Summary

• Integrated safety features including critical analog parameter monitoring, fail-safe state machine, and advanced watchdog to reduce software complexity for dual-core lock-step MCUs.
• Supports ultra-low-power saving modes with multiple wake-up sources such as CAN, LIN, IOs, and Long Duration Timer.
• Includes battery voltage sensing and MUX output pins for system diagnostics.
• Compliant with AEC-Q100 Grade 0 automotive qualification standards.

Power Management - Specialized Applications

• Power Train systems
• ASIL B or D functional safety applications
• MCU power supply and management

Power Management - Specialized Procurement Notes

Verify the specific suffix 'NAE' against the official NXP datasheet to confirm pinout and packaging details. Ensure the design environment meets the Grade 0 thermal requirements of TA=150°C. Confirm compatibility with the target MCU's SPI interface for control and diagnostics. Check for RoHS compliance status in the latest product documentation before integration.

Power Management - Specialized Selection Notes

Select this component when operating temperatures exceed Grade 1 limits, requiring TA=150°C capability. Choose the 1.5A SMPS variant if the target MCU core current demand exceeds 0.8A but remains below 2.2A. Verify that the required topology (non-inverting buck-boost or standard buck) aligns with the input voltage range of 2.7V to 40V. Ensure the application utilizes CAN FD or LIN for communication needs.
