MLX80050中文资料LIN System Basis IC Transceiver 5V/70mA数据手册Melexis规格书

描述 Description

The new Melexis MLX80050 extends its successful 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 5V voltage regulator with RESET output for the connected microcontroller.
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.
Our MLX80050 achieves world leading ESD robustness of >20kV with direct discharge as well as >15KV with indirect discharge according to IEC61000-4-2.
