General Description
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 con-
troller, 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 com-
munication up to 20kbaud, and include slew-rate limit-
ed 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 func-
tionally 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.
