MCP2004AT-E/MD

Drivers, Receivers, Transceivers Overview

The MCP2004AT-E/MD is a LIN bus transceiver compliant with specifications 1.3, 2.0, and 2.1, as well as SAE J2602. It supports baud rates up to 20 Kbaud and operates on a continuous supply voltage of 6.0V to 27.0V. The device features 43V load dump protection and high ESD immunity, rated at 20 kV on VBB and 14 kV on LBUS per IEC 61000-4-2. It includes automatic thermal shutdown, low-power modes drawing approximately 5µA in standby, and interfaces directly with PIC® MCU EUSART and standard USARTs.

Drivers, Receivers, Transceivers Feature Summary

• Compliant with LIN Bus Specifications 1.3, 2.0, and 2.1, and SAE J2602 standards for automotive and industrial applications.
• Features FAULT/TXE pin for fault detection and transmitter enable control, supporting wake-up on falling edge of LBUS.
• Provides robust protection including 43V load dump tolerance, battery short circuit protection, and ground loss protection.
• Integrates internal pull-up resistor and diode on the LIN bus pin, eliminating the need for external components.

Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring reliable LIN communication
• Industrial control networks utilizing serial bus speeds up to 20 Kbaud
• Microcontroller interfacing via EUSART or standard USART protocols

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm package integrity and pin alignment against datasheet specifications. Ensure storage conditions meet moisture sensitivity requirements prior to assembly. Check for end-of-life status implications regarding long-term supply availability.

Drivers, Receivers, Transceivers Selection Notes

Select this model when FAULT/TXE functionality is required for system diagnostics. Compare against MCP2003 variants if WAKE pin support is preferred over fault reporting. Verify temperature range compatibility for -40°C to +125°C operation. Ensure interface logic levels match the connected microcontroller's TTL requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2003/4/3A/4A family of LIN bus transceivers. It shares core electrical characteristics with siblings like the MCP2004 but differs in wake-up logic and diagnostic pins. The 'A' suffix indicates rising-edge wake-up capability, while the base model uses falling-edge detection.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include MCP2004B and ATA663211. Note that the datasheet explicitly recommends using these alternatives as the MCP2004 series is not recommended for new designs.
