ec7oic305aMelexis introduced a four-channel LIN transceiver IC. It combines four LIN transceivers on one die and enables the development of simpler and more cost effective multi-LIN network master modules. Integrated 1K LIN master termination resistors and decoupling diodes further reduce system costs. This four-channel LIN transceiver is produced in 0.8µ HV-CMOS technology and is based on the single channel transceiver TH8082. The EMC behavior of LIN Bus ICs is critical in automotive applications. The MLX80001 design exhibits robustness when subjected to the injection of high frequency disturbances. The IC has also achieved low electromagnetic emission to further simplify the design challenges of networked communication in hostile automotive environments. For the data transmission according SAEJ2602, a special low slew mode is available. The MLX80001 meets the automotive temperature range of -40°C to 125°C and has on-chip protection against over-temperature, 40V load dump and LIN short to ground. The integrated standby management assures that the MLX80001 can “wake up” from the LIN bus itself or directly from a connected microcontroller or other external source. Typical current consumption in sleep mode is as low as 20 µA.
