A 10-bit identifier (6 address, 2 parity, start-stop) is used to select the desired node. >> The combination of voltage regulator and bus transceiver make it ideal for a powerful and inexpensive cost effective slave node in a LIN Bus system. An undervoltage detection is implemented to disable transmission if V S falls below 5V, in order to avoid false bus messages. The supply current in Sleep Mode is typically 10µA and 57µA in Silent Mode. In summary, the LIN bus is attractive because it uses a simple 1-wire bus; it operates with the basic automotive battery supply; data synchronizes without a crystal reference; and no license fee is required unlike with CAN and other networks.
