GENERAL DESCRIPTION
The TJA1020 is the interface between the LIN
master/slave protocol controller and the physical bus in a
Local Interconnect Network (LIN). It is primarily intended
forin-vehiclesub-networksusingbaudratesfrom2.4 upto
20 Kbaud.
The transmit data stream of the protocol controller at the
TXD input is converted by the LIN transceiver into a bus
signal with controlled slew rate and wave shaping to
minimize EME. The LIN bus output pin is pulled HIGH via
an internal termination resistor. For a master application
an external resistor in series with a diode should be
connected between pin INH or pin BAT and pin LIN. The
receiver detects the data stream at the LIN bus input pin
and transfers it via pin RXD to the microcontroller.
In normal transceiver operation the TJA1020 can be
switched in the normal slope mode or the low slope mode.
In the low slope mode the TJA1020 lengthens the rise and
fall slopes of the LIN bus signal, thus further reducing the
already very low emission in normal slope mode.
In sleep mode the power consumption of the TJA1020 is
verylow,whereasinfailuremodesthepowerconsumption
is reduced to a minimum.
