MAX13053A
MAX13054A
+5V, 2Mbps CAN Transceiver with ±65V
Fault Protection, ±25V CMR, and ±25kV ESD
General Description
The MAX13053A and MAX13054A are +5V CAN (Control
Area Network) transceivers with integrated protection
for industrial applications. These devices have extended
±65V fault protection for equipment where overvoltage
protection is required. It also incorporates high ±25kV
ESD HBM and an input common mode range (CMR) of
±25V, exceeding the ISO11898 specification of -2V to
+7V. This makes these parts well suited for applications
that are in electrically noisy environments, where the
ground planes are shifting relative to each other. This
family features a variety of options to address common
CAN application requirements; logic-level supply input
VL for interfacing with 1.62V to 5.5V logic, low-current
standby mode, silent-mode to disable the transmitter, and
a slow slew rate to minimize EMI.
These devices operate at a high-speed CAN data rate,
allowing up to 2Mbps on small networks. Maximum speed
on large networks may be limited by the number of nodes
in a network, type of cabling, stub length, and other factors.
These transceivers include a dominant timeout to prevent
bus lockup caused by controller error or by a fault on
the TXD input. When TXD remains in the dominant state
(low) for longer than TDOM, the driver is switched to the
recessive state, releasing the bus. The MAX13053A
features a S pin where it enables and disables the
transmitter for applications where you need the
transceiver to receive only. The MAX13054A features a
STBY pin for 3 modes of operation; standby mode for low
current consumption, normal high speed mode, or a slow
slew rate mode when an external 26.1kΩ is connected
between ground and STBY pin.
The MAX13053A and MAX13054A are available in a
standard 8-pin SOIC package, and operate over the
-40°C to +125°C temperature range.

Note 1: All units are 100% production tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 2: Not production tested. Guaranteed at TA = 25°C.
Note 3: LED full-scale current maximum value is subjected to string number, LED number per string, and LX current limit. In SMBus
modes, if the total load is heavier than eight strings with ten WLEDs per string at 25mA LED current, upon step-up regulator
input VS removal, an OC fault may occur, resulting in SMBus status register OV_CURR and FAULT bits being set to 1 and
violating SMBus specifications.

MAX13053A
MAX13054A
+5V, 2Mbps CAN Transceiver with ±65V
Fault Protection, ±25V CMR, and ±25kV ESD
Detailed Description
The MAX13053A and MAX13054A are a family of fault
protected CAN transceivers designed for harsh industrial
applications with a number of integrated robust protection
feature set. These devices provide a link between the
CAN protocol controller and the physical wires of the bus
lines in a control area network (CAN). They can be used
for DeviceNet applications as well.
The two CAN transceivers are fault protected up to ±65V,
making it suitable for applications where overvoltage
protection is required. These devices are rated up to a
high ±25kV ESD of HBM (human body model), suitable
for protection during the manufacturing process, and even
in the field where there is human interface for installation
and maintenance. In addition, a common mode voltage
of ±25V enables communication in noisy environments
where there are ground plane differences between different
systems due to close proximity of heavy equipment
machinery or operation from different transformers. The
devices' dominant timeout prevents the bus from being
blocked by a hung-up microcontroller, and the outputs
CANH and CANL are short-circuit, current-limited, and
are protected against excessive power dissipation by
thermal shutdown circuitry that places the driver outputs
in a high-impedance state.
Both devices can operate up to 2Mbps, while the
MAX13054A has an option to slow the slew rate to 8V/μs
to minimize EMI, enabling the use of unshielded-twisted
or parallel cable. The MAX13054A features a standby
mode where it shuts off the transmitter and reduces the
current to 45μA typical. These CAN transceivers have a
VL pin where an integrated logic level translator enable
it to interface with low voltage microcontrollers down to
1.8V ±10%.
±65V Fault Protection
These devices feature ±65V of fault protection. CANH and
CANL data lines are capable of withstanding a short from
-65V to +65V. This extended overvoltage range makes it
suitable for applications where accidental shorts to power
supply lines are possible due to human intervention.
Transmitter
The transmitter converts a single-ended input signal
(TXD) from the local CAN controller to differential outputs
for the bus lines CANH and CANL. The truth table for the
transmitter and receiver is provided in Table 1.
Transmitter Output Protection
The MAX13053A and MAX13054A protect the transmitter
output stage against a short-circuit to a positive or negative
voltage by limiting the driver current. Thermal shutdown
further protects the devices from excessive temperatures
that may result from a short or high ambient temperature.
The transmitter returns to normal operation once the
temperature is lowered below the threshold.
Transmitter-Dominant Timeout
The devices feature a transmitter dominant timeout (tDOM)
that prevents erroneous CAN controllers from clamping
the bus to a dominant level by maintaining a continuous
low TXD signal. When TXD remains in the dominant state
(low) for greater than 2.5ms typical tDOM, the transmitter is
disabled, releasing the bus to a recessive state (Figure 4).
After a dominant timeout fault, the transmitter is re-enabled
when receiving a rising edge at TXD. The transmitter
dominant timeout limits the minimum possible data rate to
9kbps for standard CAN protocol.
Receiver
The receiver reads the differential input from the bus line
CANH and CANL and transfers this data as a singleended output RXD to the CAN controller. It consists of a
comparator that senses the difference VDIFF = (CANHCANL), with respect to an internal threshold of 0.7V. If
VDIFF > 0.9V, a logic-low is present on RXD. If VDIFF
< 0.5V, a logic-high is present. The CANH and CANL
common-mode range is ±25V. RXD is a logic-high when
CANH and CANL are shorted or terminated and undriven.

Fault Protection, ±25V CMR, and ±25kV ESD
Standby Mode (MAX13054A)
Drive STBY pin high for standby mode, which switches
the transmitter off and the receiver to a low current and
low-speed state. The supply current is reduced during
standby mode. The bus line is monitored by a low differential
comparator to detect and recognize a wakeup event on
the bus line. Once the comparator detects a dominant
bus level greater than 2.5μs typical tWAKE, RXD pulls low.
Drive the STBY low for normal operation.
Slow Slew Rate (MAX13054A)
Connect a 26.1kΩ resistor between ground and the STBY
pin. The STBY pin voltage should be between 0.1V to
0.6V to remain in slow slew rate. This will change the
MAX13054A with a slow slew rate of 8V/μs for rising edge
compared with normal mode at 180V/μs. For falling edge,
the slow slew rate is 20V/μs compared with normal mode
at 140V/μs.
Silent Mode (MAX13053A)
Drive S high to place the MAX13053A in silent mode. This
disables the transmitter regardless of the voltage level at
TXD. However, RXD is still active and monitors activity on
the bus line.
Logic Compatibility
A separate input VL allows the MAX13053A and
MAX13054A to communicate with logic systems down to
1.62V while operating up to a +5.5V supply. This provides
a reduced input voltage threshold to the TXD, STBY, and
S inputs, and provides a logic-high output at RXD compatible
with the microcontroller's supply rail. The logic compatibility
eliminates an external logic level translator and longer
propagation delay due to level shifting. Connect VL to
VDD to operate with +5V logic systems.
Applications Information
Reduced EMI and Reflections
In multidrop CAN applications, it is important to maintain
a single linear bus of uniform impedance that is properly
terminated at each end. A star, ring or tree configuration
should never be used. Any deviation from the end-to-end
wiring scheme creates a stub. High-speed data edges on
a stub can create reflections back down to 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 short as
possible, especially when operating with high data rates.
