SLIS128C – NOVEMBER 2011 – REVISED JULY 2015 SN65HVDA100-Q1 LIN Physical Interface
1 Features 3 Description 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 …
