• Local Wake−up: Rising or falling edge on input WAKE
(levels maintained for a certain period).
• Remote Wake−up from CAN Bus: A message with five
consecutive dominant bits.
On a wake−up request the transceiver will set the output
on Pin INH high which can be used to activate the external
supply voltage regulator. Note: Pin INH is also set similarly
as an after wake up event by V
BAT
voltage being below the
battery power on flag level. (See FLAG_VBAT in Figure 5)
If V
CC
is provided, the wake−up request can be read on the
ERR
or RXD outputs so the external microcontroller can
wake−up the transceiver (switch to normal operating mode)
via Pins STB
and EN.
In the low power modes the failure detection circuit
remains partly active to prevent increased power
consumption in the event of failures 3, 3a, 4, and 7.
The go−to−sleep−mode is only a transition mode. The Pin
INH stays active for a limited time. During this time the
circuit can still go to another low−power mode. After this
time the circuit goes to the sleep−mode. In case of a wake up
request (from BUS or WAKE
Pin) during this transition
time, the wake−up request has higher priority than
go−to−sleep and INH will not be deactivated.
Behavior in Case of Missing Supplies
If V
CC
is below the threshold level FLAG_V
CC
, the signals
on pins STB
and EN will internally be set to low-level to
provide fail safe functionality. In this way, a low-power mode
will be forced in case of missing/failing V
CC
supply.
Similarly, missing/failing V
BAT
supply – i.e. V
BAT
being
below FLAG_V
BAT
level - will lead to a fail-safe behavior of
the transceiver by forcing a low-power mode.
A forced low-power in case of missing supplies
guarantees that the transceiver will in no way disturb the
other CAN nodes when the local electronic unit looses
ground or battery connection.

Power−On
After power−on (V
BAT
switched on) the signal on Pin INH
will become high and an internal power−on flag will be set.
This flag can be read in the power−on standby mode via pin
ERR
(STB = 1; EN = 0) and will be reset by entering the
normal operating mode.
Protections
A current limiting circuit protects the transmitter output
stages against short circuit to positive and negative battery
voltage. If the junction temperature exceeds a maximum
value, the transmitter output stages are disabled and flagged
on the ERR
pin. Because the transmitter is responsible for
the major part of the power dissipation, this will result in
reduced power dissipation and hence a lower chip
temperature. All other parts of the IC will remain operating.
The Pins CANH and CANL are protected against
electrical transients that may occur in an automotive
environment.

ELECTRICAL CHARACTERISTICS
Definitions
All voltages are referenced to GND (Pin 13). 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.
