MAX13053/MAX13054
Industry-Standard High-Speed CAN
Transceivers with ±80V Fault Protection
General Description
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 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 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 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
common-mode 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.

MAX13050/MAX13052/
MAX13053/MAX13054
Detailed Description
The MAX13050/MAX13052/MAX13053/MAX13054 ±80V
fault-protected CAN transceivers are ideal for industrial
network applications where overvoltage protection is
required. These devices provide a link between the CAN
protocol controller and the physical wires of the bus lines
in a control area network (CAN). These devices can be
used for DeviceNet applications, requiring data rates up
to 1Mbps.
The devices’ dominant timeout prevents the bus from
being blocked by a hungup microcontroller. If the TXD
input is held low for greater than 1ms, the transmitter
becomes disabled, driving the bus line to a recessive
state. The MAX13054 +3.3V logic input allows the device
to communicate with +3.3V logic, while operating from
a +5V supply. The MAX13050 and MAX13052 provide
a split DC-stabilized voltage. The MAX13053 has a
reference output that can be used to bias the input of a
CAN controller’s differential comparator.
All devices can operate up to 1Mbps (high-speed mode).
The MAX13052 slope-control feature allows the user to
program the slew rate of the transmitter for data rates
of up to 500kbps. This reduces the effects of EMI, thus
allowing the use of unshielded-twisted or parallel cable.
The MAX13050/MAX13052 and MAX13054 standby
mode shuts off the transmitter and switches the receiver
to a low-current/low-speed state.
The device input common-mode range is greater than
±12V, exceeding the ISO11898 specification of -2V to +7V,
and feature ±8kV Contact Discharge protection, making
these devices ideal for harsh industrial environments.
±80V Fault Protected
The devices feature ±80V fault protection. This extended
voltage range of CANH, CANL, and SPLIT allows use
in high-voltage systems and communication with highvoltage buses.
Operating Modes
High-Speed Mode
The devices can achieve transmission rates of up to
1Mbps when operating in high-speed mode. Drive STBY
low to operate the MAX13050 and MAX13054 in highspeed operation. Connect RS to ground to operate the
MAX13052 in high-speed mode.
Slope-Control Mode (MAX13052)
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 high-frequency

a parallel pair of wires as bus lines. The slew rate can be
approximated using the formula below:
SR(V / µs) =

R RS
where, SR is the desired slew rate and RRS is in kΩ.
Standby Mode (MAX13050/MAX13052/MAX13054)
In standby mode (RS or STBY = high), the transmitter
is switched off and the receiver is switched to a lowcurrent/low-speed state. The supply current is reduced
during standby mode. The bus line is monitored by a lowdifferential comparator to detect and recognize a wakeup event on the bus line. Once the comparator detects
a dominant bus level greater than tWAKE, RXD pulls low.
Drive STBY high for standby mode operation for the
MAX13050 and MAX13054. Apply a logic-high to RS to
enter a low-current standby mode for the MAX13052.
Silent Mode S (MAX13053)
Drive S high to place the MAX13053 in silent mode.
When operating in silent mode, the transmitter is disabled
regardless of the voltage level at TXD. RXD however, still
monitors activity on the bus line.
Common-Mode Stabilization (SPLIT)
SPLIT provides a DC common-mode stabilization
voltage of 0.5 x VCC when operating in normal mode.
SPLIT stabilizes the recessive voltage to 0.5 x VCC for
conditions when the recessive bus voltage is lowered,
caused by an unsupplied transceiver in the network with
a significant leakage current from the bus lines to ground.
Use SPLIT to stabilize the recessive common-mode
voltage by connecting SPLIT to the center tap of the split
termination, see the Typical Operating Circuits. In standby
mode or when VCC = 0, SPLIT becomes high impedance.

DISABLED
The CAN transceivers provide a transmitter dominant
timeout function that prevents erroneous CAN controllers
from clamping the bus to a dominant level by a continuous
low TXD signal. When the TXD remains low for the 1ms
maximum timeout period, the transmitter becomes disabled,
thus driving the bus line to a recessive state (Figure 3). The
transmitter becomes enabled upon detecting a rising edge
at TXD.

Reference Output (MAX13053)
MAX13053 has a reference voltage output (REF) set to
0.5 x VCC. REF can be utilized to bias the input of a CAN
controller’s differential comparator, and to provide power
to external circuitry.
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.
www.maximintegrated.com
The receiver reads differential inputs from the bus lines
(CANH, CANL) and transfers this data as a single-ended
output (RXD) to the CAN controller. It consists of a
comparator that senses the difference VDIFF = (CANH
- CANL) with respect to an internal threshold of 0.7V. If
this difference is positive (i.e., VDIFF > 0.7), a logic-low is
present at RXD. If negative (i.e., VDIFF < 0.7V), a logichigh is present.
The CANH and CANL common-mode range is greater
than ±12V. RXD is logic-high when CANH and CANL are
shorted or terminated and undriven.

+3.3V Logic Compatibility (MAX13054)
A separate input, VCC2, allows the MAX13054 to
communicate with +3.3V logic systems while operating from
a +5V supply. This provides a reduced input voltage threshold
to the TXD and STBY inputs, and provides a logic-high output
at RXD compatible with the microcontroller’s system voltage.
The logic compatibility eliminates longer propagation delay
due to level shifting. Connect VCC2 to VCC to operate the
MAX13054 with +5V logic systems.

Driver Output Protection
The 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, current-limit protection prevents
destruction of the transmitter output stage. Upon removal
of a short, the CAN transceiver resumes normal operation.

If the junction temperature exceeds +165°C, the driver
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 IC
resumes normal operation when the junction temperature
drops below the thermal-shutdown hysteresis, and upon
the CAN transceiver detecting a rising edge at TXD.

Applications Information
Reduced EMI and Reflections
In slope-control mode, the MAX13052’s CANH and CANL
outputs are slew-rate limited, minimizing 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 4. 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
MAX13052 to minimize any possible noise coupling at
the input.
Industry-Standard High-Speed CAN
Transceivers with ±80V Fault Protection
ESD Protection
ESD-protection structures are incorporated on CANH and
CANL 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 against ±8kV ESD Contact Discharge
without damage. After an ESD event, the MAX13050/
MAX13052/MAX13053/MAX13054 continue working without
latchup. ESD protection can be tested in several ways. The
CANH and CANL inputs are characterized for protection to
±8kV using the IEC 61000-4-2 Contact Discharge Method per
IBEE Test facility.
ESD Test Conditions
ESD performance depends on a number of conditions.
Contact Maxim for a reliability report that documents test
setup, methodology, and results.
Human Body Model
Figure 5 shows the IEC 61000-4-2 Contact Discharge Model,
and Figure 6 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.
Power Supply and Bypassing
These devices require no special layout considerations
beyond common practices. Bypass VCC and VCC2 to
GND with a 0.1μF ceramic capacitor mounted close to the
IC with short lead lengths and wide trace widths.
