The MLX80020 is a physical layer device for a single wire data link capable of operating in applications using baud rates from 1kBd to 20kBd. The MLX80020 is compatible to LIN2.x as well as to the SAE J2602 specifications.
Because of the very low power consumption of the MLX80020 in the sleep mode it’s suitable for ECU applications with hard standby current requirements. The implemented high resistive termination in sleep mode as well as the driving capability of the INH pin allows a comfortable handling of LIN short circuits to GND. In order to reduce the power consumption in case of failure modes, the integrated sleep timer takes care for switching the ECU into the most power saving sleep mode after power on or wake up events that are not followed by a mode change response of the microcontroller. The MLX80020 has an improved EMI performance and ESD robustness.
The MLX80020 version with the ordering code extension ‘A’ is suitable for applications with baud rates up to 19.2kBaud.
The version of the MLX80020 with the ordering code extension ‘B’ is optimized for baud rates up to 10.4kBaud as specified in the SAE J2602 standard.
