MC35FS6516NAER2

Power Management - Specialized Overview

The MC35FS6516NAER2 is a System Basis Chip (SBC) from the NXP FS6500 family, designed for automotive applications. It integrates a DC/DC switch-mode power supply with a 1.5A Vcore output and a Low Dropout Regulator (LDO). The device supports ASIL B/D safety requirements and features an integrated CAN FD and LIN physical interface compliant with ISO11898-2, -5, and LIN 2.2 standards. It operates within a supply voltage range of 2.7V to 40V and provides MCU core voltages from 1V to 5V. The component is rated for an ambient operating temperature of -40°C to 150°C, meeting 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 power conversion.
• Includes advanced functional safety mechanisms such as critical analog parameter monitoring, a fail-safe state machine, and an advanced watchdog.
• Features integrated CAN FD and LIN transceivers that comply with latest automotive OEM EMC and ESD standards.
• Supports multiple low-power wake-up sources including CAN, LIN, I/O, and a long-duration timer.

Power Management - Specialized Applications

• Power Train control systems
• ASIL B/D ready embedded controllers
• MCU power supply and management in automotive ECUs

Power Management - Specialized Procurement Notes

Verify the specific suffix 'R2' indicates reel packaging versus other variants. Confirm the exact current rating configuration matches the design requirement, as the FS6500 family includes 0.8A, 1.5A, and 2.2A options. Ensure the thermal grade aligns with the target application's ambient temperature constraints.

Power Management - Specialized Selection Notes

Select this component when ASIL B/D compliance and high-temperature operation (150°C TA) are required. Compare against MC33FS65xx variants if lower temperature ratings (125°C TA) suffice. Verify compatibility with the target MCU's SPI interface and voltage requirements before finalizing the bill of materials.
