Melexis推出物理层器件MLX80020BA
The MLX80020BA is a physical layer device for a single wire data link capable of operating in applications using baud rates of 19.2kBd. The MLX80020BA is compatible to LIN2.x specifications used by European OEMs.
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.
