The MAX13050/MAX13052/MAX13053/MAX13054 are
pin-for-pin compatible, industry-standard, high-speed,
control area network (CAN) transceivers with extended
±80V fault protection. These products are ideal automotive
and industrial network applications where overvoltage
protection is required. These CAN transceivers provide a
link between the CAN protocol controller and the physical
wires of the bus lines in a CAN. These devices can be
used for +12V/+42V battery, automotive, and DeviceNet®
applications, requiring data rates up to 1Mbps.
The CAN transceivers have an input common-mode
range greater than ±12V, exceeding the ISO11898
specification of -2V to +7V, and feature ±8kV ESD protection,
making these devices ideal for harsh automotive
and industrial environments.
The CAN transceivers provide a dominant timeout function
that prevents erroneous CAN controllers from clamping
the bus to a dominant level if the TXD input is held low
for greater than 1ms. The MAX13050/MAX13052 provide
a SPLIT pin used to stabilize the recessive commonmode
voltage. The MAX13052 also has a slope-control
mode that can be used to program the slew rate of the
transmitter for data rates of up to 500kbps. The
MAX13053 features a silent mode that disables the transmitter.
The MAX13053 also has a reference output that
can be used to bias the input of older CAN controllers
that have a differential comparator. The MAX13054 has a
separate dedicated logic input, VCC2, allowing interfacing
with a +3.3V microcontroller.
The MAX13050/MAX13052/MAX13053/MAX13054 are
available in an 8-pin SO package and are specified to
operate in the -40°C to +85°C and the -40°C to +125°C
temperature ranges.
