MC35FS6501NAE

Power Management - Specialized Overview

The MC35FS6501NAE is a Grade 0 automotive System Basis Chip (SBC) from the FS6500 family, designed for power train applications. It integrates a DC/DC switch-mode power supply (SMPS) with a 1.5 A output current capability to supply MCU cores within a 1.0 V to 5.0 V range. The device operates on an input voltage of 2.7 V to 40 V and supports LQFP-48EP surface-mount packaging. It features high-temperature tolerance up to TA = 150 °C and TJ = 175 °C, compliant with AEC-Q100 Grade 0 standards.

Power Management - Specialized Feature Summary

• Integrates a flexible SMPS pre-regulator supporting non-inverting buck-boost and standard buck topologies for efficient MCU core power delivery.
• Includes integrated CAN FD and LIN physical interfaces compliant with ISO 11898-2, -5, and LIN 2.2/2.1/J2602-2 standards.
• Provides advanced functional safety measures targeting ASIL B/D applications, including critical analog parameter monitoring and fail-safe state machines.

Power Management - Specialized Applications

• Automotive power train systems
• MCU power supply in high-temperature environments
• ASIL B/D functional safety applications

Power Management - Specialized Procurement Notes

Verify the specific suffix 'NAE' against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with AEC-Q100 Grade 0 thermal requirements for your application environment. Confirm that the 1.5 A DCDC output meets the target MCU's peak current demands during operation.

Power Management - Specialized Selection Notes

Select this component when a higher DCDC output current of 1.5 A is required compared to the 0.8 A variant. It is suitable for designs needing Grade 0 automotive qualification with extended temperature ranges. Consider the LQFP-48EP package for space-constrained PCB layouts requiring robust thermal performance.

Power Management - Specialized Part Context

This part belongs to the FS6500 series of Safety Power System Basis Chips. It complements other variants like the MC33FS6501NAE (Grade 1, 0.8 A) and MC35FS6512NAE (Grade 0, 1.5 A). The series provides integrated power management and communication interfaces for modern automotive microcontrollers.

Power Management - Specialized Replacement Considerations

The MC33FS6501NAE serves as a Grade 1 alternative with lower current capacity. For direct functional substitution within Grade 0 designs requiring identical pinout and features, verify cross-reference data sheets for exact electrical equivalence.
