MC33FS6507NAE

Power Management - Specialized Overview

The MC33FS6507NAE is a System Basis Chip (SBC) from the FS6500 series by NXP Semiconductors, designed for automotive applications. It integrates a DC/DC switch-mode power supply (SMPS) with an output current of 0.8 A for MCU core voltage regulation. The device operates within an input voltage range of 2.7 V to 40 V and supports output voltages from 1 V to 5 V. It features integrated CAN FD and LIN physical interfaces, advanced safety mechanisms for ASIL B/D readiness, and multiple linear regulators. The component is housed in an LQFP-48EP package and is rated for operation between -40°C and +125°C.

Power Management - Specialized Feature Summary

• Integrates a high-efficiency DC/DC SMPS regulator capable of delivering up to 0.8 A for MCU core power.
• Includes built-in CAN FD and LIN transceivers compliant with ISO11898-2/-5 and LIN 2.2 standards.
• Provides comprehensive safety features including a fail-safe state machine and critical analog parameter monitoring.
• Supports low-power modes with multiple wake-up sources such as CAN, LIN, I/O, and long-duration timers.

Power Management - Specialized Applications

• Automotive powertrain control units
• Body control modules requiring robust power management
• Safety-critical embedded systems with ASIL B/D requirements

Power Management - Specialized Procurement Notes

Verify the specific suffix 'NAE' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad configuration. Ensure the selected variant meets the required automotive qualification level (AEC-Q100 Grade 0 or 1) for your target operating temperature range. Cross-reference the part number with the latest revision history to avoid obsolete packaging or material changes.

Power Management - Specialized Selection Notes

Select this model when a dedicated DC/DC converter is preferred over a linear regulator for the MCU core to improve efficiency. The 0.8 A output current is suitable for mid-range microcontrollers. Consider the integrated CAN FD and LIN interfaces if reducing external component count is a priority. Verify that the LQFP-48EP package fits the PCB footprint constraints and thermal dissipation requirements of the design.

Power Management - Specialized Part Context

The MC33FS6507NAE belongs to the FS6500 family of SMARTMOS devices, which are multi-output power supply ICs. This family is characterized by its integration of power management, communication interfaces, and safety logic into a single chip. The FS6500 series is widely used in automotive electronics to simplify system architecture and enhance reliability through integrated diagnostic capabilities.

Power Management - Specialized Replacement Considerations

Check the FS6500 product selection guide for variants with different SMPS currents (e.g., 1.5 A or 2.2 A) or LDO-only options like the FS4500 series. Ensure any substitute maintains the same LQFP-48EP package and pinout compatibility. Verify that alternative parts support the required CAN FD and LIN interface specifications.
