Overview

The MCP2003B-E/MC is a high-performance LINbus transceiver designed for bidirectional communication between a microcontroller and the LIN bus. It supports data rates up to 20kBaud and is engineered for extreme robustness in harsh automotive and industrial environments, featuring high immunity to electromagnetic interference and load dump protection up to 60V.

Why Choose This Part

This transceiver offers exceptional durability with 60V load dump protection and high ESD immunity, reducing the need for external protection components. Its ultra-low standby current of 5uA makes it suitable for battery-critical applications, while the small 2x3 DFN package saves significant PCB real estate.

Applications

Automotive Body Electronics
Ideal for door modules, seat controls, and climate systems where cost-effective, low-speed networking is required.
Industrial Sensor Networks
Used in distributed industrial control systems for long-cable communication with high noise immunity.
Power Seat and Mirror Control
Handles peripheral control in vehicle cabins with minimal wiring overhead and low standby current.
