• Includes advanced functional safety measures such as critical analog parameter monitoring, a fail-safe state machine, and an advanced watchdog.
• Features integrated CAN FD and LIN physical interfaces compliant with latest automotive OEM standards for EMC and ESD.

Power Management - Specialized Applications

• Power Train systems
• ASIL B/D ready applications
• High-temperature automotive electronics

Power Management - Specialized Procurement Notes

Verify the specific suffix CAE corresponds to the required package and tape/reel configuration against the official NXP datasheet. Confirm that the Grade 0 qualification meets the target ambient temperature requirements of TA=150°C for the specific application environment. Ensure compatibility with the intended MCU's SPI interface and voltage levels.

Power Management - Specialized Selection Notes

Select this component when operating temperatures exceed Grade 1 limits, requiring TA=150°C capability. Choose the DC/DC variant over LDO versions if higher efficiency or input voltages above 36V are needed. Verify that the 800 mA core current meets the MCU peak demand and that the integrated safety features align with the system's ASIL requirements.
