The recessive BUS level is generated from the integrated 30k pull-up resistor in series with
an active diode. This diode protects against reverse currents on the bus line in case of a volt-
age difference between the bus line and VSUP (V
resistor is necessary to use the IC as a LIN slave. If this IC is used as a LIN master, the LIN
pin is terminated by an external 1 k resistor in series with a diode to VBAT.
As PWM communication directly over the LIN transceiver in both directions is possible, there
is no TXD timeout feature implemented in the LIN transceiver.
