MC35FS4507NAE

Power Management - Specialized Overview

The MC35FS4507NAE is a Grade 0 automotive System Basis Chip (SBC) from the FS4500 family, designed for ASIL B/D applications. It operates within an ambient temperature range of -40°C to 150°C and supports junction temperatures up to 175°C. The device features a flexible SMPS pre-regulator with non-inverting buck-boost or standard buck topologies, supplying MCU cores between 1.0V and 5.0V via SMPS (0.8A/1.5A) or LDO (0.5A). It integrates CAN FD and LIN physical interfaces compliant with ISO 11898-2/-5 and LIN 2.2 standards. Input voltage ranges from 2.7V to 40V, with output voltages adjustable from 1V to 5V.

Power Management - Specialized Feature Summary

• Integrated safety mechanisms including critical analog parameter monitoring, fail-safe state machine, and advanced watchdog to reduce software complexity for dual-core lock-step MCUs.
• High-temperature capability compliant with AEC-Q100 Grade 0 automotive qualification standards.
• Ultra-low-power saving modes with multiple wake-up sources such as CAN, I/Os, and Long Duration Timer.

Power Management - Specialized Applications

• Automotive powertrain control systems
• ASIL B or D functional safety applications
• MCU power supply and management in harsh environments

Power Management - Specialized Procurement Notes

Verify the specific suffix 'NAE' against the official NXP datasheet to confirm package type and tape/reel specifications. Ensure the design accounts for the Grade 0 thermal limits (TA=150°C, TJ=175°C). Confirm compatibility with the target MCU's SPI interface for diagnostics. Check for RoHS3 compliance status in the latest manufacturing documentation.

Power Management - Specialized Selection Notes

Select this component when high-temperature operation up to 150°C ambient is required. It is suitable for designs needing integrated CAN FD and LIN transceivers alongside power regulation. Consider the SMPS flexibility for input voltage variations up to 40V. Evaluate if the 0.8A or 1.5A SMPS current ratings meet the core load requirements.
