3. General Description

The MLX80004(2) is a quad/dual LIN transceiver physical layer device for a single wire data link capable of operating in

applications using baud rates up to 20kBd. It is compliant to LIN2.x as well as to the SAE J2602 specifications. The IC

furthermore can be used in ISO9141 systems. The MLX80004 is functionally compatible to the MLX80001 quad master

LIN transceiver.

The device is flexible for use in LIN – master applications and slave applications as well.

Due to the integrated master termination and the high ESD/EMC robustness of the device a minimum space and

number of external components is required.

The number of LIN – channels can be easily adapted on the application requirements by combinations of quad and dual

channel devices within the same foot print.

Because of the very low power consumption of the MLX80004 while being in sleep mode it’s suitable for ECU

applications with hard standby current requirements. The implemented high resistive LIN - termination in sleep mode as

well as the RxD dominant time-out feature 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 IC into the most power saving sleep mode after Power-On or Wake-Up events are not followed by a mode change

response of the microcontroller.

The MLX80004/2 has an improved EMI performance and ESD robustness according to the OEM Common Hardware

Requirements for LIN in Automotive Applications Rev.1.2.

By using the MODE0/1 pins the application can be easily adapted on the required baud rate in order to optimize the

EMC emissions. A high speed Flash Mode with disabled slew rate control is available as well.

To fulfill different OEM requirements, the integrated master termination can be disabled and external master resistors

and decoupling diodes can be used. In this mode the MLX80004/2 can be used in slave applications as well.
