±80V Fault-Protected Can Transceiver
with Autobaud
The MAX13051 ±80V fault-protected CAN transceiver
with autobaud is ideal for device net and other industrial network applications where overvoltage protection is
required. The MAX13051 provides a link between the
CAN protocol controller and the physical wires of the
bus lines in a control area network (CAN).
The MAX13051 features three different modes of operation: high speed, slope control, and standby. Highspeed mode allows data rates up to 1Mbps. The
slope-control mode can be used to program the slew
rate of the transmitter for data rates of up to 500kbps,
reducing the effects of EMI and allowing the use of
unshielded-twisted or parallel cable. In standby mode,
the transmitter shuts off and a low-power receiver monitors the bus, waiting for a wake-up signal.
The MAX13051 provides a transmitter data (TXD) 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
MAX13051 also provides an autobaud feature allowing
the microcontroller to compute the incoming baud rate
without destroying CAN protocol communication. The
MAX13051 input common-mode range is greater than
±12V, exceeding the ISO 11898 specification of -2V to
+7V, and features ±6kV Human Body Model protection,
making these devices ideal for harsh environments. The
MAX13051 is available in an 8-pin SO package and is
specified from the -40°C to +85°C and -40°C to +125°C
temperature ranges.

Detail Description
±80V Fault Tolerant
The MAX13051 features ±80V fault protection. This
extended voltage range of CANH and CANL allows
communication in high-voltage systems up to 80V.
Operating Modes
High-Speed Mode
The MAX13051 can achieve transmission rates of up to
1Mbps when operating in high-speed mode. To operate in high-speed mode, short RS to ground.
Slope-Control Mode
Connect a resistor from RS to ground to select slopecontrol mode (Table 1). In slope-control mode, CANH
and CANL slew rates are controlled by the resistor,
(16kΩ ≤ RRS ≤ 200kΩ), connected between RS and
GND. Controlling the rise and fall slopes reduces highfrequency EMI and allows the use of an unshieldedtwisted pair or a parallel pair of wires as bus lines. The
slew rate can be approximated using the formula
below:
8
SR (V / µs) ≈
250
RRS
where, SR is the desired slew rate and RRS is in kΩ.
Standby Mode
In standby mode (RS = high), the transmitter is
switched off and the receiver is switched to a low-current/low-speed state. The supply current reduces to
15µA to detect and recognize a wake-up event on the
bus line. During standby mode, the bus line is monitored with a low-differential comparator. Once the comparator detects a dominant bus level greater than
tWAKE, RXD pulls low.
Autobaud Mode
The MAX13051 logic-controlled autobaud input allows
a microcontroller to compute the incoming baud rate
without destroying CAN protocol communication. When
operating in autobaud mode, TXD is looped back to
RXD without applying a differential signal at CANH and
CANL. See Figure 4.

Transmitter
The transmitter converts a single-ended input (TXD)
from the CAN controller to differential outputs for the
bus lines (CANH, CANL). The truth table for the transmitter and receiver is given in Table 2.
TXD Dominant Timeout
The MAX13051 provides a transmitter-dominant timeout
that prevents erroneous CAN controllers from clamping
the bus to a dominant level by maintaining a continuous
low TXD signal. When the TXD remains in the dominant
state for greater than 1ms (max), the transmitter
becomes disabled, driving the bus line to a recessive
state (Figure 5). After a dominant timeout fault, the
MAX13051’s transmitter becomes enabled upon
detecting a rising edge at TXD.
Receiver
The receiver reads differential inputs from the bus lines
(CANH, CANL) and transfers this data as a singleended output (RXD) to the CAN controller. It consists of
a comparator that senses the difference, V DIFF =
(CANH - CANL), with respect to an internal threshold of
0.7V. If this difference is positive, (VDIFF > 0.9V), a
logic-low is present at RXD. If negative, (VDIFF < 0.5V),
a logic-high is present. The receiver always echoes the
CAN bus data when not operating in autobaud mode.

The CANH and CANL common-mode range is ±12V
exceeding the ISO 11898 specification at -2V to +7V.
RXD is logic-high when CANH and CANL are shorted
or undriven.
Driver Output Protection
The MAX13051 current-limiting feature protects the
transmitter output stage against a short circuit to a positive and negative battery voltage. Although the power
dissipation increases during this fault condition, currentlimit protection prevents destruction of the transmitter
output stage. Upon removal of a short, the MAX13051
resumes normal operation.
Thermal Shutdown
If the junction temperature exceeds +165°C, the device
is switched off. The hysteresis is approximately 13°C,
disabling thermal shutdown once the temperature
drops below 152°C. In thermal shutdown, CANH and
CANL go recessive. After a thermal-shutdown event,
the MAX13051 resumes normal operation when the
MAX13051
RL = 120Ω
In slope-control mode, the CANH and CANL outputs
are slew-rate limited, minimizing high-frequency EMI,
and reducing reflections caused by improperly terminated cables.
In multidrop CAN applications, it is important to maintain a direct point-to-point wiring scheme. A single pair
of wires should connect each element of the CAN bus,
and the two ends of the bus should be terminated with
120Ω resistors, see Figure 6. A star configuration
should never be used.
Any deviation from the point-to-point wiring scheme
creates a stub. The high-speed edge of the CAN data
on a stub can create reflections back down the bus.
These reflections can cause data errors by eroding the
noise margin of the system.
Although stubs are unavoidable in a multidrop system,
care should be taken to keep these stubs as small as
possible, especially in high-speed mode. In slope-control mode, the requirements are not as rigorous, but
stub length should still be minimized.
Layout Consideration
CANH and CANL are differential signals and steps
should be taken to insure equivalent parasitic capacitance. Place the resistor at RS as close as possible to
the MAX13051 to minimize any possible noise coupling
at the input.

Figure 8. Human Body Model Current Waveform
ESD Test Conditions
The MAX13051 requires no special layout considerations beyond common practices. Bypass VCC to GND
with a 0.1µF ceramic capacitor mounted closely to the
IC with short lead lengths and wide trace widths.
ESD performance depends on a number of conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
±6kV ESD Protection
Figure 7 shows the Human Body Model, and Figure 8
shows the current waveform it generates when discharged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the device through a
1.5kΩ resistor.
ESD protection structures are incorporated on all inputs
to protect against ESD encountered during handling and
assembly. CANH and CANL inputs have extra protection
to protect against static electricity found in normal operation. Maxim’s engineers have developed state-of-the-art
structures to protect these pins (CANH, CANL) against
±6kV ESD without damage. ESD protection can be tested in several ways. The CANH and CANL inputs are
characterized for protection to ±6kV using the Human
Body Model.
