Application information
L6382D5
12/21
Summarizing:
–
The high-voltage start-up generator is active;
–VREF is disabled with additional sinking circuit on pin VREF enabled;
–
TPR is disabled;
–
OCP is disabled;
–
The drivers are disabled.
5.2.1
SAVE Mode
This mode is entered after the VCC voltage reaches the turn-on threshold; the VREF is
enabled in low current source mode to supply the
C 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:
–
The high-voltage start-up generator is cycling;
–VREF is enabled in low source current capability (IREF ≤ 10mA);
–
TPR circuit is disabled;
–
OCP is disabled;
–
The drivers are disabled.
If the VCC voltage falls below the VREF(OFF) threshold, the device enters the start-up mode.
5.2.2
OPERATING Mode
After 10
s in save mode 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
–VREF is enabled in high source current mode (IREF < 30mA)
–
TPR circuit is enabled
–
OCP is enabled
–
The drivers are enabled
If there is no switching activity on LGI for more than 100
s, the IC returns in save mode.
5.2.3
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:
1.
VCC < VccOff (Under Voltage fault on Supply),
2.
VREF < 3.2V (Under Voltage fault on VREF)
