Maxim MAX3057ASA ±80v fault-protected, 2mbps, low-supply current can transceiver Datasheet

MAX3050/MAX3057
±80V Fault-Protected, 2Mbps, Low-Supply
Current CAN Transceivers
General Description
Features
●● ±80V Fault Protection for 42V Systems
The MAX3050 and MAX3057 interface between the
CAN protocol controller and the physical wires of the bus
lines in a control area network (CAN). They are primarily
intended for systems requiring data rates up to 2Mbps
and feature ±80V fault protection against shorts in highvoltage power buses. They provide differential transmit
capability to the bus and differential receive capability to
the CAN controller.
●● Four Operating Modes:
• High-Speed Operation Up to 2Mbps
• Slope-Control Mode to Reduce EMI
(40kbps to 500kbps)
• Standby Mode
• Low-Current Shutdown Mode
●● AutoShutdown when Device is Inactive (MAX3050)
The MAX3050 and MAX3057 have four modes of operation:
high speed, slope control, standby, and shutdown. Highspeed mode allows data rates up to 2Mbps. In slope-control
mode, data rates are 40kbps to 500kbps, so the effects of
EMI are reduced, and unshielded twisted or parallel cable
can be used. In standby mode, the transmitters are shut off
and the receivers are put into low-current mode. In shutdown
mode, the transmitter and receiver are switched off.
●● Automatic Wake-Up from Shutdown (MAX3050)
●● Thermal Shutdown
●● Current Limiting
●● Fully Compatible with the ISO 11898 Standard
Ordering Information
PART
The MAX3050 has an AutoShutdown™ function that puts
the device into a 15ms shutdown mode when the bus or
CAN controller is inactive for 4ms or longer.
The MAX3050 and MAX3057 are available in an 8-pin
SO package and are specified for operation from -40°C
to +125°C.

MAX3050/MAX3057
±80V Fault-Protected, 2Mbps, Low-Supply
Current CAN Transceivers
Detailed Description
The transceivers are designed to operate from a single
+5V supply and draw 56mA of supply current in dominant
state and 3.6mA in recessive state. In standby mode,
supply current is reduced to 135μA. In shutdown mode,
supply current is 15μA.
The MAX3050 and MAX3057 interface between the
protocol controller and the physical wires of the bus lines
in a CAN. They are primarily intended for applications
requiring data rates up to 2Mbps and feature ±80V fault
protection against shorts in high-voltage systems. This
fault protection allows the devices to withstand up to ±80V
with respect to ground with no damage to the device.
The built-in fault tolerance allows the device to survive
in industrial environments with no external protection
devices. The devices provide differential transmit capability to the bus and differential receive capability to the CAN
controller. (See Figure 4.)
CANH and CANL are output short-circuit current-limited
and are protected against excessive power dissipation by
thermal-shutdown circuitry that places the driver outputs
into a high-impedance state.
Fault Protection
The MAX3050 and MAX3057 feature ±80V fault protection. This extended voltage range of CANH and CANL
bus lines allows use in high-voltage systems and com
munication with high-voltage buses. If data is transmitting
at 2Mbps, the fault protection is reduced to ±70V.
The device has four modes of operation: high speed, slope
control, standby, and shutdown. In high-speed mode, slew
rates are not limited, making 2Mbps transmission speeds
possible. Slew rates are controlled in slopecontrol mode,
minimizing EMI and allowing use of unshielded twisted or
parallel cable. In standby mode, receivers are active and
transmitters are in high impedance. In shutdown mode,
transmitters and receivers are turned off.
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 1.

* As defined by ISO, bus value is one of two complementary logical values: dominant or recessive. The dominant value represents
the logical 0 and the recessive represents the logical 1. During the simultaneous transmission of the dominant and recessive bits, the
resulting bus value is dominant.
High Speed
Connect RS to ground to set the MAX3050 and MAX3057
to high-speed mode. When operating in high-speed
mode, the MAX3050 and MAX3057 can achieve transmission rates of up to 2Mbps. Line drivers are switched on
and off as quickly as possible. However, in this mode, no
measures are taken to limit the rise and fall slope of the
data signal, allowing for potential EMI emissions. If using
the MAX3050 and MAX3057 in high-speed mode, use
shielded twistedpair cable to avoid EMI problems.
Slope Control
Connect a resistor from RS to ground to select slopecontrol mode. (See Table 2.) In slope-control mode, the
gates of the line drivers are charged with a controlled
current, proportional to the resistor connected to the RS
pin. Transmission speed ranges from 40kbps to 500kbps.
Controlling the rise and fall slope reduces EMI and allows
the use of an unshielded twisted pair or a parallel pair of
wires as bus lines. The transfer function for selecting the
resistor value is given by:
RRS (kΩ) = 12000/speed (in kbps).
Receiver
The receiver reads differential input 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 ΔV = (CANH - CANL) with
respect to an internal threshold of 0.7V. If this difference is
positive (i.e., ΔV > 0.7V) a logic-low is present at the RXD
pin. If negative (i.e., ΔV < 0.7V), a logic-high is present.
The receiver always echoes the transmitted data.
The CANH and CANL common-mode range is -7V to
+12V. RXD is logic high when CANH and CANL are shorted or terminated and undriven. If the differential receiver
input voltage (CANH - CANL) is less than or equal to 0.5V,
RXD is logic high. If (CANH - CANL) is greater than or
equal to 0.9V, RXD is logic low.
Standby
The MAX3050 and MAX3057 transmitters are threestated, and the receivers are active in standby. This allows
the device to read data on the bus while reducing power
consumption.
See the Slew Rate vs. RRS graph in the Typical Operating
Characteristics section.
Receivers take up to 10ms to wake up from standby
mode. Therefore, the first bits of information read off the
bus when coming out of standby can be lost.
Shutdown
Thermal Shutdown
In shutdown mode, the device is switched off. The outputs
are high impedance to ± 80V. The MAX3057 features a pullup at SHDN. If shutdown is forced low and then left floating,
the device remains in shutdown until SHDN is forced high.
If the junction temperature exceeds +160°C, the device is
switched off. The hysteresis is approximately 20°C, disabling thermal shutdown once the temperature reaches
+140°C.

AutoShutdown (MAX3050)
To manage power consumption, AutoShutdown puts the
device into shutdown mode after it has been inac-tive
for a period of time. The value of an external capacitor
(CSHDN) connected to SHDN determines the threshold
of inactivity time, after which the AutoShutdown triggers.
Floating SHDN allows the MAX3050 to automatically
change from active mode to shutdown.

Drive SHDN high to turn the MAX3050 on and disable
AutoShutdown.
When the MAX3050 is in shutdown mode, only the wakeup comparator is active, and normal bus communication
is ignored. The remote master of the CAN system wakes
up the MAX3050 with a signal greater than 9V on CANH.
Internal circuitry in the MAX3050 puts the device in normal operation by driving SHDN high.

The MAX3057 does not have the AutoShutdown feature.
Driver Output Protection
The MAX3050 and MAX3057 have several features that
protect them from damage. Thermal shutdown switches
off the device and puts CANH and CANL into high
impedance if the junction temperature exceeds +160°C.
Thermal protection is needed particularly when a bus line
is short-circuited. The hysteresis for the thermal shutdown
is approximately 20°C.

Additionally, a current-limiting circuit protects the transmitter output stage against short-circuit to positive and
negative battery voltage. Although the power dissipation
increases during this fault condition, this feature prevents
destruction of the transmitter output stage.

In slope-control mode, the CANH and CANL outputs are
slew-rate limited, minimizing EMI and reducing reflections
caused by improperly terminated cables. In general, a
transmitter’s rise time relates directly to the length of an
unterminated stub, which can be driven with only minor
waveform reflections. The following equation expresses
this relationship conservatively:

Length = tRISE / (15ns/ft)
where tRISE is the transmitter’s rise time.

The MAX3050 and MAX3057 require no special layout
considerations beyond common practices. Bypass VCC to
GND with a 1μF ceramic capacitor mounted close to the
IC with short lead lengths and wide trace widths.
