Feedback Suppression
The logic unit described in Table 3 constantly ensures that
dominant symbols on one bus line are transmitted to the
other bus line without imposing any priority on either of the
lines. This feature would lead to an “interlock” state with
permanent dominant signal transmitted to both bus lines, if
no extra measure is taken.
Therefore feedback suppression is included inside the
logic unit of the transceiver. This block masksout reception
on that bus line, on which a dominant is actively transmitted.
The reception becomes active again only with certain delay
after the dominant transmission on this line is finished.
PoweronReset (POR)
While Vcc voltage is below the POR level, the POR
circuit makes sure that:
The counters are kept in the reset mode and stable state
without current consumption
Inputs are disabled (don’t care)
Outputs are high impedant; only Rx0 = highlevel
Analog blocks are in power down
Oscillator not running and in power down
CANHx and CANLx are recessive
VREF output high impedant for POR not released
Over Temperature Detection
A thermal protection circuit is integrated to prevent the
transceiver from damage if the junction temperature
exceeds thermal shutdown level. Because the transmitters
dissipate most of the total power, the transmitters will be
switched off only to reduce power dissipation and IC
temperature. All other IC functions continue to operate.
Fault Behavior
A fault like a short circuit is limited to that bus line where
it occurs; hence data interchange from the protocol IC to the
other bus system is not affected.
When the voltage at the bus lines is going out of the normal
operating range (12 V to +12 V), the receiver is not allowed
to erroneously detect a dominant state.
Short Circuits
A currentlimiting circuit protects the transmitter output
stage from damage caused by an accidental shortcircuit to
either positive or negative supply voltage, although power
dissipation increases during this fault condition.
The pins CANHx and CANLx are protected from
automotive electrical transients (according to “ISO 7637”).
ELECTRICAL CHARACTERISTICS
Definitions
All voltages are referenced to GND. Positive currents
flow into the IC. Sinking current means that the current is
flowing into the pin. Sourcing current means that the current
is flowing out of the pin.
