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.

•

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.

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.
