MC33909L5AD

Power Management - Specialized Overview

The MC33909L5AD is a System Basis Chip (SBC) from NXP USA Inc., designed for automotive applications. It integrates a DC/DC converter, multiple switches, and communication interfaces including CAN and LIN. The device operates within a supply voltage range of 3.5V to 28V and supports an operating temperature range of -40°C to 125°C. It features a 7mA power supply current and is housed in a 48-LQFP exposed pad package.

Power Management - Specialized Feature Summary

• Integrates DC/DC converter and multiple switch-to-ground outputs for power management
• Supports CAN and LIN communication protocols for automotive networking
• Compliant with EU environmental standards including ROHS and REACH directives

Power Management - Specialized Applications

• Automotive system basis chip implementations
• Power management modules requiring integrated switching capabilities
• Vehicle networks utilizing CAN and LIN bus architectures

Power Management - Specialized Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm the specific suffix 'L5AD' matches project requirements as the MC33909 family has been withdrawn; ensure replacement compatibility with recommended UJA113x series if sourcing new designs. Check for RoHS compliance documentation upon receipt.

Power Management - Specialized Selection Notes

Select this component only if legacy support for the withdrawn MC33909 family is required. For new designs, evaluate the recommended UJA113x series replacements. Ensure the 48-LQFP package fits the PCB layout constraints. Verify that the integrated CAN and LIN transceivers meet the specific network speed and isolation requirements of the target application.

Power Management - Specialized Part Context

The MC33909 product family has been officially withdrawn by NXP. The manufacturer recommends using the UJA113x system basis chip series as direct replacements. This transition affects long-term availability and support for the MC33909L5AD variant.

Power Management - Specialized Replacement Considerations

NXP officially recommends the UJA113x system basis chip series as replacements for the withdrawn MC33909 family. Evaluate pinout compatibility and feature parity between the MC33909L5AD and specific UJA113x variants before implementation.
