limitation and thermal shutdown. An internal pullup resistor
with a serial diode structure is integrated, so no external
pullup components are required for the application in a slave
node. 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.
from external disturbance, guaranteeing communication
during external disturbance.
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. Due to
excessive power dissipation in the transmitter, software is
advised to monitor this bit and turn the transmitter off
immediately.
The LIN driver is a low-side MOSFET with internal current
The LIN terminal offers high susceptibility immunity level
The LIN transmitter circuitry is enabled by setting the
