Local Interconnect Network (LIN) was developed to address the need for cost-effective networks to create communication between the devices where speed is not a critical requirement. LIN is a broadcasting, single wire, serial network protocol that supports communications up to 19.2Kbit/s at a bus length of 40 meters. LIN bus is typically a multi-point, low-cost communication line used for expansion within the peripheral devices in conjunction with the CAN bus in an automotive system.
LIN is a serial communication based, leader-follower network where a leader sends a header signal to up to 15 follower nodes which triggers the follower nodes to send a signal back to leader. This is referred to as a LIN cluster. LIN clusters can communicate with each other when connected via a CAN bus.
The LIN ESD diode is connected between the Ground and LIN bus, which in turn is pulled up to VBAT as the previous image illustrates.
