The new Melexis MLX80031 extends the LIN transceiver and system basis product line for the simple and effective development of LIN slaves.
This IC transceiver combines a physical layer LIN transceiver according to LIN 2.x as well as SAEJ2602 with a 3.3V/70mA voltage regulator with RESET output for the connected microcontroller and a window watchdog.
This enhanced IC transceiver is optimized in accordance with the increased EMC requirements for single wire bus systems as well as the “Hardware Requirements for LIN, CAN and Flexray Interfaces in Automotive Applications” defined from German OEMs.
The MLX80031 achieves world leading ESD robustness of >20kV with direct discharge as well as >15kV with indirect discharge according to IEC61000-4-2.
