4.2 Ignition Power Management Quick Guide
Startup conditions from the IGNITION signal:

IGNITION startup signal must be valid during 3 sec. (anti‐noise protection).

Typically, the system can start only from the IGNITION signal because the startup PIC controller is
disconnected from the power source.
Startup Procedure by Ignition
9VDC~60VDC
