MCP2003Microchip Technology Inc. announced the MCP2003 and MCP2004 (MCP2003/4) stand-alone LIN transceivers.  These AEC-Q100-certified devices are 3rd party-LIN/J2602 approved and satisfy the stringent requirements of automotive manufacturers, worldwide.  The transceivers are compliant with the LIN Bus 1.X/2.0/2.1 and SAE J2602 standards, and feature industry-leading ESD and EMC performance for reliable communication in extremely harsh environments.  Their current-consumption ratings are among the lowest in the LIN transceiver market, allowing for extended battery life and more efficient non-ignition-switched applications.

The market momentum for LIN continues to show strong growth and acceptance in all regions around the world.  According to the research firm Strategy Analytics*, LIN represents the second largest market segment in networked automotive applications, in terms of number of nodes.  The MCP2003/4 family represents Microchip’s third generation of LIN/SAE J2602 transceivers, following the Company’s previous-generation MCP2021/2 transceivers with an integrated voltage regulator.  The MCP2003/4 family’s industry-leading EMC performance results in more robust designs that are less susceptible to system faults.  This feature also lowers costs by making systems more efficient, with few to no external components required.

 “Microchip is committed to aligning our new LIN products with customer requirements, giving them a competitive, high-performance LIN solution,” said Bryan J. Liddiard, vice president of marketing with Microchip’s Analog and Interface Products Division.  “This is exemplified by the release of our MCP2003/4 stand-alone LIN transceivers, which meet and exceed major automotive manufacturer requirements, while maintaining industry-leading low power consumption, and high ESD and EMC performance.  These stand-alone transceivers complement our rapidly growing LIN portfolio, giving customers more flexibility when designing their LIN systems.”
