Local Wakeup: Rising or falling edge on input WAKE
(levels maintained for a certain period).
Remote Wakeup from CAN Bus: A message with five
consecutive dominant bits.
On a wakeup 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 VBAT voltage being below the
battery power on flag level. (See FLAG_VBAT in Figure 5)
If VCC is provided, the wakeup request can be read on the
ERR or RXD outputs so the external microcontroller can
wakeup 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 gotosleepmode is only a transition mode. The Pin
INH stays active for a limited time. During this time the
circuit can still go to another lowpower mode. After this
time the circuit goes to the sleepmode. In case of a wake up
request (from BUS or WAKE Pin) during this transition
time, the wakeup request has higher priority than
gotosleepand INH will not be deactivated.
Behavior in Case of Missing Supplies
If VCC is below the threshold level FLAG_VCC, 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 VCC supply.
Similarly, missing/failing VBAT supply – i.e. VBAT being
below FLAG_VBAT 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.

PowerOn
After poweron (VBAT switched on) the signal on Pin INH
will become high and an internal poweron flag will be set.
This flag can be read in the poweron 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.
