LIN PHYSICAL LAYER
The LIN bus pin provides a physical layer for single-wire
communication in automotive applications. The LIN physical
layer is designed to meet the LIN physical layer specification.
The LIN driver is a low side MOSFET with internal current
limitation and thermal shutdown. An internal pull-up resistor
with a serial diode structure is integrated, so no external pull-
up components are required for the application in a slave
mode. The fall time from dominant to recessive, and the rise
time from recessive to dominant is controlled. The symmetry
between both slew rate controls is guaranteed.
The slew rate can be selected for optimized operation at
10 and 20 kBit/s, as well as high baud rates for test and
programming. The slew rate can be adapted with 2 bits
SRS[1:0] in the System Control Register. The initial slew rate
is optimized for 20 kBit/s.
The LIN pin offers high susceptibility immunity level from
external disturbance, guaranteeing communication during
external disturbance.
The LIN transmitter circuitry is enabled by setting the
PSON bit in the System Control Register (SYSCTL).
If the transmitter works in the current limitation region, the
LINCL bit in the System Status Register (SYSSTAT) is set
and the LIN transceiver is disabled after a certain time.
For improved performance and safe behavior when the
LIN bus shorts to Ground, or LIN bus leakage during low
power mode, the internal pull-up resistor on the LIN pin is
disconnected from VSUP and a small current source keeps
the LIN bus at recessive level. In case of a LIN bus short to
GND, this feature will reduce the current consumption in
STOP and SLEEP modes.
Figure 16. LIN Interface
TXD Pin
The TXD pin is the MCU interface to control the state of the
LIN transmitter (see Figure 2, page 2). When TXD is LOW,
the LIN pin is low (dominant state). When TXD is HIGH, the
LIN output MOSFET is turned off (recessive state). The TXD
pin has an internal pull-up current source in order to set the
LIN bus to recessive state in the event, for instance, the
microcontroller could not control it during system power-up or
power-down.
