MAX13051
±80V Fault-Protected Can Transceiver
with Autobaud
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 Table 2.
TXD Dominant Timeout
The MAX13051 provides a transmitter-dominant timeout
that prevents erroneous CAN controllers from clamping
the bus to a dominant level by maintaining a continuous
low TXD signal. When the TXD remains in the dominant
state for greater than 1ms (max), the transmitter
becomes disabled, driving the bus line to a recessive
state (Figure 5). After a dominant timeout fault, the
MAX13051’s transmitter becomes enabled upon
detecting a rising edge at TXD.
Receiver
The receiver reads differential inputs from the bus lines
(CANH, CANL) and transfers this data as a single-
ended output (RXD) to the CAN controller. It consists of
a comparator that senses the difference, VDIFF =
(CANH - CANL), with respect to an internal threshold of
0.7V. If this difference is positive, (VDIFF > 0.9V), a
logic-low is present at RXD. If negative, (VDIFF < 0.5V),
a logic-high is present. The receiver always echoes the
CAN bus data when not operating in autobaud mode.
