MLX80001
4-channel Master LIN Transceiver
3.5 Pin LIN
The LINx pins are the four physical interfaces to the automotive environment. The related circuitry consists of
three parts:
• Transmitter with slew rate control
The slew rate of the transmitter is configurable by the MODE0/1 pins and depends from the application.
• Receiver
The receiver guarantees the specified input threshold levels and a very high robustness to external
disturbances.
• Termination
This circuitry contains the master pull up resistor and decoupling diodes. The integrated solution allows a
very comfortable control of failure situations, see description below. To guarantee the specified value of +/-
10% and to minimize the power dissipation, this circuitry is adjustable on wafer level. In order to allow a
battery current limitation in failure situations, a high resistive termination is placed in parallel to the master
pull up resistor.
