SLIS128C November 2011 – July 2015 SN65HVDA100-Q1
The SN65HVDA100 device is the Local Interconnect Network (LIN) physical interface, which integrates the serial transceiver with wakeup and protection features. The LIN bus is a single-wire bidirectional bus typically used for low-speed in-vehicle networks using data rates from 2.4 kbps to 20 kbps. The LIN protocol output data stream on TXD is converted by the SN65HVDA100 into the LIN bus signal through a current-limited wave-shaping driver as outlined by the LIN Physical Layer Specification. The receiver converts the data stream from the LIN bus and outputs the data stream through RXD. The LIN bus has two states: dominant state (voltage near ground) and recessive state (voltage near battery). In the recessive state, the LIN bus is pulled high by the internal pullup resistor (30 kΩ) and series diode, so no external pullup components are required for slave applications. Master applications require an external pullup resistor (1 kΩ) plus a series diode per the LIN specification.
