Bit Name Bit No. Description
1
N/A 7 Reserved.
ISCOFF_INT 6 Independent sink off.
1 = indicates that the controller has ramped all the independent sinks designated in Register 0x04 and
Register 0x05 to off.
0 = the controller has not ramped all designated independent sinks to off.
BLOFF_INT 5 Backlight off.
1 = indicates that the controller has faded the backlight sinks to off.
0 = the controller has not completed fading the backlight sinks to off.
SHORT_INT 4
Short-circuit error.
1 = a short-circuit or overload condition on VOUT or current sinks was detected.
0 = no short-circuit or overload condition was detected.
TSD_INT 3 Thermal shutdown.
1 = device temperature is too high and has been shut down.
0 = no overtemperature condition was detected.
OVP_INT 2 Overvoltage interrupt.
1 = charge-pump output voltage has exceeded V
OVP

0 = charge-pump output voltage has not exceeded V

N/A

Interrupt bits are cleared by writing a 1 to the flag; writing a 0 or reading the flag has no effect.
Interrupt Enable (INT_EN)—Register 0x03

Bit Name Bit No. Description
N/A 7 Reserved.
ISCOFF_IEN 6 Automated ISC off indicator.
1 = the automated independent sink off indicator is enabled.
0 = the automated independent sink off indicator is disabled.
BLOFF_IEN 5 Automated backlight off indicator.
1 = the automated backlight off indicator is enabled.
0 = the automated backlight off indicator is disabled.
When this bit is set, an INT is generated anytime that a backlight fade-out is over. This occurs after an automated
fade-out or after the completion of a backlight dimming profile. This is useful to synchronize the complete turn off
for the backlights with other devices in the application.
SHORT_IEN 4 Short-circuit interrupt enabled. When the SHORT_INT status bit is set after an error condition, an interrupt is raised
to the host if the SHORT_IEN flag is enabled.
1 = the short-circuit interrupt is enabled.
0 = the short-circuit interrupt is disabled (SHORT_INT flag is still asserted).
TSD_IEN 3 Thermal shutdown interrupt enabled. When the TSD_INT status bit is set after an error condition, an interrupt is
raised to the host if the TSD_IEN flag is enabled.
1 = the thermal shutdown interrupt is enabled.
0 = the thermal shutdown interrupt is disabled (TSD_INT flag is still asserted).
