MC35FS4502CAE

Power Management - Specialized Overview

The MC35FS4502CAE is a Grade 0 automotive System Basis Chip (SBC) from the FS4500 family, designed for ASIL B/D applications. It integrates a linear voltage regulator providing 0.5 A to the MCU core, with an output range of 1.0 V to 5.0 V. The device supports a maximum input operating voltage of 36 V and operates within an ambient temperature range of -40°C to +150°C, reaching a junction temperature of 175°C. It features integrated CAN FD and LIN physical interfaces compliant with ISO 11898-2, -5, and LIN 2.2 standards. The component is housed in an LQFP-48EP package.

Power Management - Specialized Feature Summary

• Integrates advanced functional safety measures targeting ASIL B or D applications
• Provides dedicated linear regulators for MCU core, auxiliary functions, and I/O supply
• Includes integrated CAN FD and LIN transceivers with EMC and ESD protection
• Features fail-safe state machine and advanced watchdog to reduce software complexity

Power Management - Specialized Applications

• Power Train systems
• ASIL B/D compliant microcontroller power management
• Automotive body electronics requiring high thermal tolerance

Power Management - Specialized Procurement Notes

Verify the specific suffix 'CAE' against official NXP documentation to confirm pinout and feature set, as variations exist within the FS4500 family. Confirm current production status, as some variants may be subject to obsolescence notices. Ensure compatibility with the target MCU's SPI interface for diagnostics and control. Validate that the Grade 0 qualification meets the specific thermal requirements of the intended application environment.

Power Management - Specialized Selection Notes

Select this component when a linear regulator topology is preferred over SMPS for the MCU core supply in high-temperature environments. It is suitable for designs requiring Grade 0 automotive qualification with TA up to 150°C. Consider this part if the application demands integrated CAN FD and LIN connectivity without external transceivers. Verify that the 0.5 A core current capability meets the MCU's peak consumption requirements.
