Key Features

  • Single LIN 2.x-compliant transceiver for automotive serial network physical layer
  • 8-pin SOIC-8 package enabling compact PCB integration in automotive body modules
  • Integrated slope control and current limiting for robust LIN bus communication
  • Supports LIN bus speeds up to 20 kbps as defined by the LIN 2.x specification
  • Single 8-pin channel transceiver with UART-compatible logic-side interface
  • RoHS-compliant Pb-free construction (JESD-609 e3)

Applications

MCP2003B-E/SN is used in automotive body electronics such as door modules, seat actuators, climate control panels, and lighting systems that communicate over the LIN bus at up to 20 kbps. It is also applied in industrial sensor networks and smart actuator interfaces where a low-cost single-wire serial bus with 8-pin SOIC simplicity is preferred over CAN or RS-485.

Frequently Asked Questions

Which LIN bus standard does MCP2003B-E/SN comply with and what maximum bus speed does it support?

MCP2003B-E/SN is compliant with the LIN 2.x specification and supports bus communication speeds up to 20 kbps. This covers standard automotive LIN applications including body control modules, window lifters, and seat position actuators that typically operate at 9.6 kbps to 19.2 kbps.

How does MCP2003B-E/SN connect to a microcontroller UART and what additional components are required?

MCP2003B-E/SN provides a UART-compatible logic interface on the MCU side and a single-wire LIN bus interface on the network side. Only a few passive components — typically a bus protection diode, a pull-up resistor, and bypass capacitors — are needed alongside the 8-pin SOIC to complete the LIN physical layer.

For an automotive seat control module design, what advantage does MCP2003B-E/SN's 8-pin SOIC package offer over larger alternatives?

The 8-pin SOIC package occupies a board footprint of approximately 5 mm × 4 mm, making it easy to integrate into compact automotive actuator modules with limited PCB area. Its small size and single-transceiver function are well matched to slave node applications where only 1 LIN channel per node is required.

What sourcing lead time should procurement teams expect for MCP2003B-E/SN and does the part have a long YTEOL horizon?

MCP2003B-E/SN has a factory lead time of approximately 8 weeks and a YTEOL (Years to End of Life) rating of 14, indicating the part is expected to remain available for at least 14 more years. This long lifecycle horizon makes it a low-risk choice for automotive programs with 10-year or more production commitments.
