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-wire mode if certain fault conditions
occur. The MAX3054/MAX3055/MAX3056 guarantee
full wake-up capability during failure modes.
The extended fault-protected voltage range of CANH
and CANL bus lines of ±80V allows for use in 42V
automotive applications. Current-limiting and thermal-
protection circuits protect the transmitter output stage
against overcurrent faults to prevent destruction of the
transmitter output stage. The CANH and CANL lines are
also protected against electrical transients that may occur
in an automotive environment.
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 pro-
vide 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 the
40kbps and 125kbps versions, a built-in slope-control
feature allows the use of unshielded cables, and receiv-
er input filters guarantee high noise immunity.
