Description
AI
The SN65HVDA195 device is the Local Interconnect Network (LIN) physical interface and MOST ECL interface, which integrates the serial transceiver with wake-up and protection features. The bus is a single-wire bidirectional bus typically used for low-speed in-vehicle networks using data rates to 20 kbps. The device can transmit with an effective data rate of 0 kbps because it does not have dominant state time-out. The protocol output data stream on TXD is converted by the SN65HVDA195 into the bus signal through a current-limited wave-shaping driver as outlined by the LIN physical layer specification revision 2.0. The receiver converts the data stream from the bus and outputs the data stream through RXD. The bus has two states: dominant state (voltage near ground) and the recessive state (voltage near battery). In the recessive state, the bus is pulled high by the SN65HVDA195 internal pullup resistor and series diode, so no external pullup components are required for responder applications. Commander applications require an external pullup resistor (1 kΩ) plus a series diode per the LIN specification.
