INTERRUPTS
There are five interrupt sources available on the ADP8860.
•
•
Main light sensor comparator: CMP_INT sets every time
the main light sensor comparator detects a threshold (L2
or L3) transition (rising or falling conditions).
Sensor Comparator 2: CMP2_INT interrupt works the
same way as CMP_INT, except the sensing input derives
from the second light sensor. The programmable thresholds
are the same as the main light sensor comparator.

The interrupt (if any) that appears on the nINT pin is deter-
mined by the bits mapped in Register INTR_EN. To clear an
interrupt, write a 1 to the interrupt in the MDCR2 register or
reset the part. Reading the interrupt, or writing a 0, has no effect.
Overvoltage protection: OVP_INT is generated when the
output voltage exceeds 5.8 V (typical).
Thermal shutdown circuit: An interrupt (TSD_INT) is
generated when entering overtemperature protection.
Short-circuit detection: SHORT_INT is generated when
the device enters short-circuit protection mode.
