Summarizing:
■
the high-voltage start-up generator is cycling;
V
REF
is enabled in low source current capability (I
REF
≤
10mA);
TPR circuit is disabled;
OCP is disabled;
the drivers are disabled.
If the Vcc voltage falls below the V
REF(OFF)
threshold, the device enters the start-upmode.

4.1.3 OPERATING Mode
After 10
μ
s in savemode and only if the votage at V
REF
is higher than 4.6V, on the falling edge on the HGI
input, the driver are enabled as well as all the IC's functions; this is the mode correspondent to the proper
lamp behaviour.
Summarizing:
HVSU is OFF
V
REF
is enabled in high source current mode (I
REF
< 30mA)
■
TPR circuit is enabled
OCP is enabled
the drivers are enabled
If there is no switching activity on LGI for more than 100
μ
s, the IC returns in save mode.

4.1.4 Shut Down
This state permits to manage the fault conditions in operatingmode and it is entered by the occurrence
on one of the following conditions:
– 1. Vcc<VccOff (Under Voltage fault on Supply),
– 2. V
REF
<3.2V (Under Voltage fault on V
REF
)
In this state the functions are:
The HVSU generator is ON
V
REF
is enabled in low source current mode (I
REF
< 10mA)
■
TPR is disabled
OCP is disabled
the drivers are disabled
In this state if Vcc reaches VccOn, the device enters the savemode otherwise, if Vcc<V
REF(OFF)
, also the
μ
C is turned off and the device will be ready to execute the Start-up sequence.
