±80V Fault-Protected/Tolerant CAN Transceivers for In-Car Applications
General Description
The MAX3054/MAX3055/MAX3056 are interfaces
between the protocol controller and the physical wires
of the bus lines in a controller area network (CAN). The
devices provide differential transmit capability and switch
to single-mode if certain fault conditions occur. The
MAX3054/MAX3055/MAX3056 guarantee full wakeup
capability during failure modes.
The extended fault-protected voltage range of CANH and
CANL bus lines of ±80V. Current-limiting and thermalpro-
tection circuits protect the transmitter output stage against
overcurrent faults to prevent destruction of the transmitter
output stage. The CANH and CANL lines are also protect-
ed against electrical transients that may occur in rugged
environments.
The transceiver provides three low-power modes that
can be entered and exited through pins STB and EN. An
output INH pin can be used for deactivation of an external
voltage regulator.
The MAX3054/MAX3055/MAX3056 are designed to provide
optimal operation for a specified data rate. The MAX3054 is
ideal for high data rates of 250kbps. The MAX3055 is used
for data rates of 125kbps and the MAX3056 is designed for
40kbps applications. For 40kbps and 125kbps versions, a
built-in slope-control feature allows the use of unshielded
cables, and receiver input filters guarantee high noise immunity.
Applications●Industrial HVAC
Features●±80V Fault Protection●Low RFI/Excellent EMC Immunity●Full Wake-Up Capability During Failure Modes●Bus Failure Management●Support Single-Wire Transmission Mode with Ground
Offset Voltages Up to 1.5V●Thermally Protected●Do Not Disturb the Bus Line when Unpowered●Low-Current Sleep and Standby Mode with Wake-Up
Through Bus Lines●Up to 250kbps Data Rate (MAX3054)●Pin and Functionally Compatible with TJA1054

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
