resumes)
0 – No fault
1 – Buck_boost output is above OVP threshold
102
101
IREG_PG_FAULT
V6V power-good fault interrupt (normal operation resumes)
0 – No fault
1 – V6V is not in regulation
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
R
0
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-
good threshold, likely to be caused by a short.
INT

98
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
97
96
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.

0
0
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.
