The Local Interconnect Network (LIN) is a serial bus protocol which is primarily intended for transmission of control related data between a number of bus nodes. A LIN sub-bus is intended for applications like seats, doors, roofs, switch panels, steering wheels, etc. Its task is to connect switches, actuators and sensors into a sub-bus that links to a main bus (e.g. a CAN bus). NXP LIN transceivers support the single wire bus protocol that applies to in-vehicle Class A buses with a single master node and multiple slave nodes.
