Summarizing:
SAVE Mode
This mode is entered after the Vcc voltage reaches the turn-on threshold; the V
enabled in low current source mode to supply the µC connected to it, whose wake-up
required current must be less than 10mA: if no switching activity is detected at LGI input, the
high voltage start-up generator cycles ON-OFF keeping the Vcc voltage between VccON
and VccSM.
Summarizing:
If the Vcc voltage falls below the V
OPERATING Mode
After 10µs in save mode and only if the voltage at V
edge on the HGI input, the drivers are enabled as well as all the IC's functions; this is the
mode correspondent to the proper lamp behavior.
Summarizing:
If there is no switching activity on LGI for more than 100µs, the IC returns in save mode.
Shut down
This state permits to manage the fault conditions in operating mode and it is entered by the
occurrence on one of the following conditions:
