Detailed Description
The MAX3058/MAX3059 interface between the protocol
controller and the physical wires of the bus lines in a
CAN. They are primarily intended for printer and tele-
com backplane applications requiring data rates up to
1Mbps. These devices provide differential transmit
capability to the bus and differential receive capability
to the CAN controller.
The MAX3058 output common-mode range is from -7V
to +12V. The MAX3059 output common-mode range is
from 0V to VCC. The MAX3059 contains an internal
switch termination resistor that makes it ideal for JetLink
applications.
The MAX3058 features four different modes of opera-
tion: high-speed, slope control, standby, and shut-
down. The MAX3059 features three different modes of
operation: high speed, slope control, and shutdown.
High-speed mode allows data rates up to 1Mbps. In
slope-control mode, the slew rate may be optimized for
data rates up 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.
The transceivers operate from a single +5V supply and
draw 40mA of supply current in dominant state and 2mA
in recessive state. In standby mode, supply current is
reduced to 15A. In shutdown mode, supply current is
1A for the MAX3058 and 5A for the MAX3059.
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.
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 trans-
mitter and receiver is given in Tables 1 and 2.
