General Description

The MAX3058/MAX3059 interface between the con-

troller area network (CAN) protocol controller and the

physical wires of the bus lines in a CAN. They are pri-

marily intended for printer and telecom backplane appli-

cations 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 V

. 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 shutdown.

The MAX3059 features three different modes of opera-

tion: 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 MAX3058/MAX3059 are available in an 8-pin SO

package and are specified over the -40°C to +125°C

temperature range.

5V, 1Mbps, Low Supply Current CAN Transceivers 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 telecom 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 V CC.
PAGE 10
MAX3058/MAX3059 5V, 1Mbps, Low Supply Current CAN Transceivers 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 ∆V = (CANH CANL) with respect to an internal threshold of 0.7V. If this difference is positive (i.e., ∆V > 0.7), a logic low is present at RXD. If negative (i.e., ∆V < 0.7V), a logic high is present.
PAGE 11
5V, 1Mbps, Low Supply Current CAN Transceivers Reduced EMI and Reflections In slope-control mode, the CANH and CANL outputs are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. In multidrop CAN applications, it is important to maintain a direct point-to-point wiring scheme. A single pair of wires should connect each element of the CAN bus, and the two ends of the bus should be terminated with 120Ω resistors. A star configuration should never be used.
