MC33665ATU4AE

Overview

The MC33665ATU4AE is a general-purpose battery management communication gateway and TPL transceiver manufactured by NXP Semiconductors. It routes messages from four independent TPL (NXP proprietary isolated daisy chain) ports to standard protocols including SPI, CAN FD, and UART. The device supports up to 10 Mbit/s SPI data rate and 5 Mbit/s CAN FD data rate. It operates within a temperature range of -40°C to +125°C and is housed in an LQFP-48 package.

Feature Summary

• Routes messages from four independent TPL daisy chain ports to standard communication protocols
• Supports SPI, CAN FD, and UART interfaces for microcontroller compatibility
• Enables message buffering and synchronization between MCU and daisy chain ports
• Compatible with MC33771C and MC33772C battery cell controllers

Applications

• Automotive Battery Management Systems (BMS)

• E-bikes and E-scooters
• Energy Storage Systems (ESS)

Procurement Notes

Verify the specific suffix 'TU' against official documentation to confirm interface configuration, as suffixes may denote variations. Ensure the component meets required automotive or industrial qualification standards if applicable. Cross-reference the datasheet for exact pinout and electrical characteristics before integration. Confirm availability through authorized distributors due to potential supply constraints.

Selection Notes

Select this component when a gateway is needed to bridge proprietary TPL networks with standard MCU interfaces like SPI, CAN FD, or UART. It is suitable for applications requiring message buffering and synchronization across multiple daisy chains. Consider compatibility with existing cell controllers such as MC33771C or MC33772C. Evaluate thermal requirements against the specified operating temperature range.
