MCP202x/MCP202xA LIN Transceivers

Microchip's MCP202x/MCP202xA LIN transceivers with voltage regulator

MCP202x/MCP202xA LIN TransceiversMicrochip's MCP2021A provides a bidirectional, half-duplex communication physical interface to an automotive and industrial Local Interconnect (LIN) and SAE J2602 bus. Operation covers LIN Bus Specification Versions 1.3, 2.0, 2.1 and SAE J2602. The device incorporates a voltage regulator with 5 V/70 mA or 3.3 V/70 mA output. The regulator is short-circuit protected and also includes thermal shutdown. The regulator has been specifically designed to operate in the automotive environment and will survive reverse battery conditions, +43 V load dump transients and double-battery jump starts. The device has been designed to meet the stringent quiescent current requirements of the automotive industry. The devices' very low emissions, excellent robustness to automotive transients, and very high ESD robustness have been confirmed by independent test authorities.

Features
  • Physical layer transceiver interface to support LIN bus specifications version 1.3, 2.0, 2.1 and SAE J2602
  • Integrated 3.3 V or 5.0 V Vreg with output current of 70 mA and current limit greater than 250 mA
  • ESD performance on Vbb & LIN pins > 15 KV (IEC 61000-4-2)
  • Meets stringent auto requirements including “OEM hardware requirements for LIN, CAN and FlexRay interfaces in automotive applications”, version 1.2, March 2011
  • Typical powerdown current < 4.5 uA
  • MCP2021A available in 8-pin PDIP, SOIC and DFN packages
    • MCP2021A-330 with 3.3 V regulator
    • MCP2021A-500 with 5 V regulator
