Analog, Mixed Signal and Power Management MC33662 LIN 2.1 / SAEJ2602-2, LIN Physical Layer Applications MC33662 Simplified Application Diagram • Automotive Market: • Body electronics (BCM, gateway, roof, door, lighting, HVAC) • Powertrain (EMS, Start&Stop), BMS • Safety & Chassis (TPMS, Seat Belt) VBAT Overview 33662 The Local Interconnect Network (LIN) is a serial communication protocol, designed to support automotive networks in conjunction with a Controller Area Network (CAN). VSUP CAN SBC or Regulator As the lowest level of a hierarchical network, LIN enables cost-effective communication with sensors and actuators when all the features of CAN are not required. WAKE VDD 12 V 5.0 V or 3.3 V The three 33662 versions are designed to operate at different maximum baud rates. The MC33662LEF and MC33662SEF offer a normal baud rate (20 kbps), and the MC33662JEF, a slow baud rate (10 kbps). They integrate a fast baud rate (above 100 kbps), as reported by the RXD pin for test and programming modes. They provide excellent EMC (Electromagnetic Compatibility) and Radiated Emission performance, ESD (Electrostatic Discharge) robustness, and safe behavior, in the event of a LIN bus short-to-ground, or a LIN bus leakage during low-power mode.
