MC33662BLEF

Drivers, Receivers, Transceivers Overview

The MC33662BLEF is a LIN Physical Layer transceiver designed for automotive applications, supporting LIN 2.0 through 2.2A and SAE J2602-2 standards. It operates at a maximum baud rate of 20 kbps with an operating voltage range of 7.0 to 18 V DC, functional up to 27 V DC, and withstands 40 V load dump conditions. The device features 5.0 V and 3.3 V compatible digital inputs, active bus wave shaping for low emissions, and high ESD immunity (up to 25 kV on VSUP). Packaged in an 8-pin SOICN, it includes overtemperature protection and supports local/remote wake-up capabilities.

Drivers, Receivers, Transceivers Feature Summary

• Compliant with LIN 2.x and ISO 17987-4:2016 standards
• Active bus wave shaping for excellent radiated emission performance
• High ESD robustness and electromagnetic interference immunity
• Low standby current in Sleep mode with overtemperature protection

Drivers, Receivers, Transceivers Applications

• Automotive body electronics including BCM, gateway, roof, door, lighting, and HVAC systems
• Powertrain applications such as EMS and start & stop systems
• Battery Management Systems (BMS)
• Safety and chassis modules like TPMS and seat belt controllers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EF' indicates a lead-free package variant when sourcing. Confirm that the 'B' designation corresponds to the 20 kbps speed grade distinct from the 10 kbps 'J' series. Ensure the order quantity aligns with the manufacturer's standard tape and reel packaging requirements for this component type.

Drivers, Receivers, Transceivers Selection Notes

Select the MC33662BLEF for designs requiring a 20 kbps LIN interface with 5.0 V or 3.3 V logic compatibility. This part is suitable for nodes needing active bus wave shaping to meet strict EMC regulations. Consider the pin-to-pin compatibility with TJA1021 if migrating existing designs. Verify thermal management needs given the -40 to 125 °C operating temperature range.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MC33662 family of LIN physical layer transceivers manufactured by NXP Semiconductors. The family includes variants with different baud rates, such as the 10 kbps MC33662BJEF and the restricted-limit MC33662S series. All variants share similar core functionalities but differ in transmission speed specifications and symmetry limits.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the device is pin-to-pin compatible with the TJA1021. Designers replacing other components should verify electrical parameter alignment with this specific reference.
