Ignition Power Management (OPTIONAL)
Startup/shutdown conditions from the IGNITION signal:
•
IGNITION Power Startup signal must be valid during 3 sec. (anti-noise protection)
•
IGNITION shutdown
–
IGNITION signal must be inactive during 3 sec, then PIC controller initiates
Power Button signal (OS must be set to shut down from the Power Button). It generates Main
Button shutdown event and then goes to complete power off.
Typically, the system can start only from IGNITION signal, because startup PIC controller is disconnected
from the power source.
The system can be switched off from:
•
Power IGNITION OFF signal.
•
ACPI OS shutdown
•
Power Button
–
generate ACPI event (OS dependent).
