MAX13021：±60V Fault-Protected LIN Transceivers

The Most Robust LIN Transceivers Available in the Industry, Offering ±60V of Overvoltage Protection and ±12kV ESD Human Body Model Protection on the Bus Pin

The MAX13020/MAX13021 ±60V fault-protected low-power local interconnect network (LIN) transceivers are ideal for use in automotive network applications where high reliability is required. The devices provide the interface between the LIN master/slave protocol controller, and the physical bus described in the LIN 2.0 specification package and SAE J2602 specification. The devices are intended for in-vehicle subnetworks with a single master and multiple slaves. The extended fault-protected voltage range of ±60V on the LIN bus line allows for use in +12V, +24V, and +42V automotive applications. The devices allow communication up to 20kbaud, and include slew-rate limited transmitters for enhanced electromagnetic emissions (EME) performance. The devices feature a low-power 4µA sleep mode and provide wake-up source detection. The MAX13020 is a pin-to-pin replacement and is functionally compatible with the Philips TJA1020. The MAX13021 includes enhanced bus dominant clamping fault management for reduced quiescent current during LIN bus shorts to GND. The MAX13020/MAX13021 are available in the 8-pin SO package, and operate over the -40°C to +125°C automotive temperature range.
