The MLX80001 is 4-channel LIN transceiver IC that significantly reduces automotive-system costs of the LIN physical layer compared to multiple single-transceiver ICs found in, for example, a body-control module. The chip combines four LIN transceivers on one die and enables the development of simpler and more cost-effective multi-LIN network master modules. Integrated 1000 LIN master termination resistors, and decoupling diodes further reduce system costs. The transceiver is produced in 0.8micron HV-CMOS technology and is based on the industry-proven single-channel transceiver TH8082. The IC exhibits excellent robustness when subjected to the injection of high-frequency disturbances. It also generates very low electromagnetic emissions, further simplifying the design challenges of networked communication in hostile automotive environments. For data transmission according to SAEJ2602, a special low-slew mode is available. The IC meets the automotive-temperature range of -40 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 device can "wake up" from the LIN bus itself or directly from a connected microcontroller or other external source. Current consumption in sleep mode is as low as 20µA.
