General Description
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 20kbd. The version of the
MLX80020 with the ordering code extension ‘B’ is optimized for baud rates up to 10.4kbd as specified in the
SAE J2602 standard.
