1 Introduction

The amount of electrical systems and components continue to grow as automobiles become more intelligent, safe, and comfortable. The growth of these components and systems demand a need for communication transceivers, to facilitate their interaction in the most advantageous way possible for manufacturers. LIN was developed to manage communication between these components and systems in an efficient and straightforward fashion, where the bandwidth and versatility of CAN was not needed; though in most instances, it is a sub-bus to the CAN bus.
