FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
on page 13, the 33399 has two operational modes, normal
and sleep, and one transitional mode, Awake.
NORMAL MODE
This is the normal transmitting and receiving mode. All
features are available.
SLEEP MODE
In this mode the transmission path is disabled and the
device is in low power mode. Supply current from VSUP is
20 A typical. Wake-up can occur from LIN bus activity, as
well as from node internal wake-up through the EN pin and
the WAKE input pin.
DEVICE POWER-UP (AWAKE TRANSITIONAL
MODE)
At system power-up (VSUP rises from zero), the 33399
automatically switches into the “Awake” mode (refer to
pin in HIGH state to VSUP level. The microcontroller of the
application then confirms the Normal mode by setting the EN
pin HIGH.
DEVICE WAKE-UP EVENTS
The device can be awakened from Sleep mode by three
wake-up events:
LIN bus activity
Internal node wake-up (EN pin)
Wake-up from WAKE pin
circuit and detail of wake-up operations.
Wake-up from LIN Bus (Awake Transitional Mode)
A wake-up from the LIN pin switching from recessive to
dominant state (switch from VSUP to GND) can occur. This
is achieved by a node sending a wake-up frame on the bus.
This condition internally wakes up the interface, which
switches the INH pin to a HIGH level to enable the voltage
regulator. The device switches into the Awake mode. The
microcontroller and the complete application power up. The
microcontroller must switch the EN pin to a HIGH level to
allow the device to leave the Awake mode and turn it into
Normal mode in order to allow communication on the bus.
Wake-up from Internal Node Activity (Normal Mode)
The application can internally wake-up. In this case, the
microcontroller of the application sets the EN pin in the HIGH
state. The device switches into Normal mode.
Wake-up from WAKE Pin (Awake Transitional Mode)
The application can wake up with the activation of an
external switch. Refer to Table 1, 8-SOICN Pin Definitions on
Figure 10. Operational and Transitional Modes State Diagram
