MFS2633AMDALADR2

Power Management - Specialized Overview

The MFS2633AMDALADR2 is an automotive Safety System Basis Chip (SBC) from the FS26 series, designed for ASIL D applications. It operates within a supply voltage range of 3.2 V to 36 V and supports a maximum input voltage of 40 V. The device integrates multiple switching regulators and LDOs, providing output currents up to 1.5 A and 800 mA, alongside lower current rails. Output voltages include fixed 3 V and 5 V options, with adjustable ranges from 800 mV to 3.35 V. It functions reliably between -40 °C and +125 °C in an LQFP-48 package.

Power Management - Specialized Feature Summary

• Provides comprehensive power management with integrated switching and linear regulators for microcontrollers and peripherals.
• Supports ASIL D functional safety requirements with dedicated monitoring circuits and fault-safe outputs.
• Enables low-power system states with configurable sleep and standby modes for extended battery life.

Power Management - Specialized Applications

• Electric Power Steering (EPS)
• Automotive domain controllers
• Safety-critical sensor nodes

Power Management - Specialized Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm package integrity upon receipt as moisture sensitivity requires proper handling. Ensure compatibility with existing board layouts before finalizing orders, as availability may be limited.

Power Management - Specialized Selection Notes

Select this variant for high-integrity systems requiring ASIL D compliance. Consider the specific regulator configurations and pinout compared to other FS26 members. Evaluate thermal performance given the LQFP-48 package constraints for your specific application environment.

Power Management - Specialized Part Context

Part of the FS26 family of Safety SBCs, offering scalable solutions for automotive electronics. Designed to replace older PMICs while providing enhanced diagnostic capabilities and lower power consumption. Compatible with standard development tools like the KITFS26SKTEVM.

Power Management - Specialized Replacement Considerations

Check for direct substitutes within the FS26 series such as MFS2633AMDA0AD or MFS2633HMDC3AD. Verify pin-to-pin compatibility and regulator specifications before substitution.
