Analog, Mixed-Signal and Power Management MC33663 LIN 2.1 / SAEJ2602-2 Dual LIN Physical Layer Overview The local interconnect network (LIN) is a serial communication protocol designed to support automotive networks in conjunction with controller area network (CAN). 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. The 33663 product line integrates two physical layer LIN bus dedicated to automotive LIN sub-bus applications. The MC33663LEF and MC33663SEF devices offer normal baud rate (20 kbps) and the MC33663JEF slow baud rate (10kbps). Both devices integrate fast baud rate (above 100 kbps) for test and programming modes. The 33663 product line offers Applications MC33663 Simplified Application Diagram • Body electronics • Body controller & gateways • Lighting modules • Door/seat module • Powertrain: VBAT • Engine management/ Start Stop • Battery management systems 33663 VSUP Regulator MCU VDD 12 V 5.0 or 3.3 V excellent electromagnetic compatibility (EMC) and radiated emission performance, electrostatic discharge (ESD) robustness and safe behavior, in the event of LIN bus short-to-ground or LIN bus leakage during low-power mode.
