Figure 4. Different Types of Wiring Failure
Low Power Modes
The transceiver provides three low power modes, which
can be entered and exited via Pins STBB and EN (see
Figure
5). (Gotosleep mode is only a transition mode.)
The sleep mode is the mode with the lowest power
consumption. Pin INH is switched to highimpedance for
deactivation of the external voltage regulator. Pin CANL is
biased to the battery voltage via Pin RTL. If the supply
voltage is provided, Pins RXD and ERR will signal the
wakeup interrupt signal.
The standby mode will react the same as the sleep mode
but with a highlevel on pin INH.
The poweron standby mode is the same as the standby
mode with the battery poweron flag instead of the wakeup
interrupt signal on Pin ERR. The output on Pin RXD will
show the wakeup interrupt. This mode is only for reading
out the poweron flag.
Wakeup request is detected by the following events:
