MAX13020/MAX13021 60V Fault-Protected LIN Transceivers General Description Features MAX13020 is a Pin-to-Pin Upgrade for TJA1020 The MAX13020/MAX13021 60V fault-protected low- power local interconnect network (LIN) transceivers are ESD Protection 12kV Human Body Model (LIN) ideal for use in automotive network applications where 4kV Contact Discharge (LIN, NWAKE, BAT) high reliability is required. The devices provide the interface between the LIN master/slave protocol con- LIN 2.0/SAE J2602 Compatible troller, and the physical bus described in the LIN 2.0 Slew-Rate Limited Transmitter for Low specification package and SAE J2602 specification. Electromagnetic Emissions (EME) The devices are intended for in-vehicle subnetworks Robust Electromagnetic Immunity (EMI) with a single master and multiple slaves. Passive Behavior in Unpowered State The extended fault-protected voltage range of 60V on TXD Dominant Timeout Function the LIN bus line allows for use in +12V, +24V, and LIN Bus Dominant Management (MAX13021 Only) +42V automotive applications. The devices allow com- Input Levels Compatible with +3.3V and +5V munication up to 20kbaud, and include slew-rate limit- Controllers ed transmitters for enhanced electromagnetic Integrated 30k Termination Resistor for Slave emissions (EME) performance. The devices feature a Applications low-power 4A sleep mode and provide wake-up Low 4A Sleep Mode with Local and Remote source detection. Wake-Up Detection The MAX13020 is a pin-to-pin replacement and is func- Wake-Up Source Recognition tionally compatible with the Philips TJA1020.
