DESCRIPTION

103

VLED_OVP

VLED buck_boost overvoltage fault interrupt (normal operation

resumes)

0 – No fault

1 – Buck_boost output is above OVP threshold

102

IREG_PG_FAULT

V6V power-good fault interrupt (normal operation resumes)

0 – No fault

1 – V6V is not in regulation

101

PROJ_ON_INT

Proj_On interrupt (part enters OFF mode)

0 – Pin is pulled high, normal mode

1 – Pin is pulled low, alerts the DPP that the DMD regulator is

about to shut down.

100

DMD_FAULT

DMD regulator fault (part enters STANDBY mode and DMD_EN

bit is cleared)

0 – No fault

1 – The inductor current is not increasing at the correct rate,

likely to be caused by an open inductor.

Or, one of the regulator outputs has dropped below the power-

INT

good threshold, likely to be caused by a short

UVLO

UVLO interrupt (sensed at VINA pin), DMD bit is cleared.

0 – Battery voltage is above the UVLO threshold

1 – Battery voltage has dropped below the UVLO threshold

BAT_LOW_WARN

Low battery warning interrupt (sensed at VINA pin, normal

operation resumes)

0 – Battery voltage is above the low-battery threshold

1 – Battery voltage has dropped below the low-battery threshold

TS_WARN

Thermal warning interrupt (normal operation resumes)

0 – Die temperature is in normal operating range

1 – Die temperature is above the HOT threshold

Or, part has not cooled down enough to recover from HOT.

TS_WARN

Thermal Warning Interrupt (normal operation resumes)

0 – Die temperature is in normal operating range

1 – Die temperature is above the HOT threshold

Or, part has not cooled down enough to recover from HOT.
