MC33889BPEG

Specialized Overview

The MC33889BPEG is a System Basis Chip (SBC) featuring a low-speed fault-tolerant CAN interface, manufactured by NXP USA Inc. It operates within a supply voltage range of 5.5 V to 18 V and supports an ambient temperature range from -40 °C to 125 °C. The device integrates a fully protected 5.0 V low-dropout regulator with a total current capability of 200 mA, including current limiting and overtemperature protection. It includes a high-side switch output capable of delivering up to 150 mA for external loads. The integrated CAN transceiver supports the CAN 2.0 A and B protocols at speeds up to 125 kbps.

Specialized Feature Summary

• Integrates a fully protected 5.0 V low-dropout regulator with current limitation and thermal monitoring.
• Includes a low-speed fault-tolerant CAN physical interface compatible with CAN 2.0 A and B protocols.
• Features four operational modes: Normal, Standby, Stop, and Sleep for optimized power management.
• Provides an internally switched high-side power supply output with external wake-up input capabilities.

Specialized Applications

• Automotive microcontroller-based systems requiring combined power management and communication.
• Module-to-module communications utilizing low-speed fault-tolerant CAN networks.
• Engine control units and small engine control applications.
• Transmission and gearbox electronic control modules.

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package and tape/reel configuration. Check for end-of-life status updates as availability may be restricted. Ensure compliance with RoHS3 and REACH regulations prior to integration into final assemblies.

Specialized Selection Notes

Select the MC33889BPEG when a fixed 5.0 V regulator and low-speed CAN interface are required. Compare differential receiver thresholds against the MC33889D variant if specific bus failure recovery characteristics are critical. Verify that the 28-SOICW package dimensions fit the target PCB layout constraints. Ensure the system design accommodates the external PNP transistor requirements for the V2 regulator function.

Specialized Part Context

This component belongs to the MC33889 family of System Basis Chips designed for automotive environments. It combines standard microcontroller peripheral functions such as protection, diagnostics, and power regulation into a single monolithic IC. The device utilizes SMARTMOS technology to provide robust performance in harsh electrical conditions typical of vehicle networks.

Specialized Replacement Considerations

The MC33889DPEG is a functional alternative within the same family. Note that the MC33889D variant exhibits different differential receiver thresholds and loop time specifications compared to the MC33889B version. Verify compatibility with existing bus termination and wake-up circuitry before substitution.
