MC33FS6505CAE

Power Management - Specialized Overview

The MC33FS6505CAE is a System Basis Chip (SBC) from the FS6500 family, designed for automotive applications. It integrates a DC/DC switch-mode power supply with a maximum output current of 0.8A to regulate MCU core voltage between 1.0V and 5.0V. The device features an integrated CAN FD physical interface compliant with ISO11898-2 and -5 standards. It includes linear regulators for auxiliary functions and I/O, battery voltage sensing, and five configurable I/O pins. The component operates within a temperature range of -40°C to +125°C ambient and supports low-power modes with multiple wake-up sources.

Power Management - Specialized Feature Summary

• Integrates a high-efficiency SMPS pre-regulator supporting non-inverting buck-boost and standard buck topologies for flexible power management.
• Includes advanced functional safety mechanisms such as a fail-safe state machine, critical analog parameter monitoring, and an advanced watchdog to support ASIL B/D readiness.
• Features an integrated CAN FD transceiver compliant with latest automotive OEM EMC and ESD standards alongside LIN physical interface capabilities.

Power Management - Specialized Applications

• Powertrain control units requiring robust power management and communication interfaces
• Body control modules needing low-power standby modes and multiple wake-up sources
• Sensor nodes utilizing the integrated linear regulators and battery voltage sensing

Power Management - Specialized Procurement Notes

Verify the specific suffix 'CAE' against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with the target MCU's SPI interface requirements for configuration and diagnostics. Check for RoHS compliance status in the latest production documentation before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component when a 0.8A DC/DC output is sufficient for the MCU core load. Compare against higher-current variants like the MC33FS6510 or MC33FS6520 if greater Vcore current is required. Consider the AEC-Q100 Grade 1 qualification for standard automotive environments. Evaluate the integrated CAN FD capability against systems requiring only legacy CAN or LIN connectivity.
