INT AND CT OUTPUTS
The INT and CT pins are open-drain outputs, and both pins
require a 10 kΩ pull-up resistor to V
UNDERTEMPERATURE AND OVERTEMPERATURE
DETECTION
The INT and CT pins have two undertemperature/overtemperature
modes: comparator mode and interrupt mode. The interrupt
mode is the default power-up overtemperature mode. The INT
output pin becomes active when the temperature is greater than
the temperature stored in the T
the temperature stored in the T
reacts after this event depends on the overtemperature mode
selected.
Figure 19 illustrates the comparator and interrupt modes for
events exceeding the T

events exceeding the T

READ
Comparator Mode
In comparator mode, the INT pin returns to its inactive status
when the temperature drops below the T
rises above the T
Putting the ADT7410 into shutdown mode does not reset the
INT state in comparator mode.
Interrupt Mode
In interrupt mode, the INT pin goes inactive when any ADT7410
register is read. Once the INT pin is reset, it goes active again
only when the temperature is greater than the temperature stored
in the T
in the T
Placing the ADT7410 into shutdown mode resets the INT pin
in the interrupt mode.
