MC33909N5ADR2

Power Management - Specialized Overview

The MC33909N5ADR2 is a System Basis Chip (SBC) from NXP, designed for automotive applications. It integrates a single CAN transceiver and an LIN transceiver with high-side driver capabilities. The device operates within a supply voltage range of 3.5V to 28V and draws a typical supply current of 7mA. It is housed in a 48-LQFP exposed pad package (7x7 mm) suitable for surface mount installation. The component supports an operating temperature range from -40°C to 125°C.

Power Management - Specialized Feature Summary

• Integrates single CAN and LIN transceivers with high-side driver functionality
• Provides comprehensive diagnostic features via SPI interface
• Includes integrated low-dropout regulator with protection mechanisms

Power Management - Specialized Applications

• Automotive body control modules
• Gateway systems requiring mixed CAN/LIN communication
• Electronic control units with high-side load driving requirements

Power Management - Specialized Procurement Notes

Verify the obsolete status of this part number before procurement planning. NXP officially recommends the UJA113x series as replacement products. Confirm availability through authorized distributors and check for lead time variations due to end-of-life status. Ensure design-in compatibility with recommended substitutes if long-term supply is required.

Power Management - Specialized Selection Notes

Select this component only if legacy support for the MC33909 family is strictly necessary. Evaluate the UJA113x series for new designs to ensure long-term availability. Consider pinout compatibility and functional equivalence when transitioning to replacement parts. Verify that the integrated CAN and LIN interfaces meet specific network topology requirements.

Power Management - Specialized Part Context

The MC33909 belongs to a withdrawn product family from NXP. It was previously used in automotive electronics requiring integrated power management and communication interfaces. The specific variant N5ADR2 denotes the tape and reel packaging configuration. Engineers should prioritize newer generations for sustainable production cycles.

Power Management - Specialized Replacement Considerations

NXP explicitly recommends the UJA113x system basis chip series as replacements for the MC33909 family. Verify functional mapping between the legacy CAN/LIN integration and the UJA113x architecture. Check for differences in pin assignments and thermal performance during substitution analysis.
