Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'MD' against official documentation, as standard listings often use 'SN'. Confirm current availability status, as this family may be marked as not recommended for new designs. Ensure compatibility with existing system requirements before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring LIN 2.1 compliance and robust transient protection. Consider the wake-up mechanism; the base MCP2003 wakes on a falling edge. Verify if the 'MD' suffix indicates a specific variant like the MCP2003A which wakes on a rising edge, ensuring it matches the system's power-down recovery strategy.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MCP2003/4/3A/4A family of LIN transceivers. It provides a physical interface between microcontrollers and the LIN bus. The family includes variants with different wake-up characteristics and fault reporting pins. This specific part is a driver-only transceiver intended for node communication in serial bus architectures.

Drivers, Receivers, Transceivers Replacement Considerations

Microchip recommends using the ATA663211 or MCP2003B for new designs instead of this family. When replacing, verify pinout compatibility and ensure the replacement supports the required LIN specification version and operating voltage range.
