INT AND CT OUTPUTS
The INT and CT pins are open drain outputs, and both pins
require a 10 k& pull-up resistor to V
DD
.
UNDERTEMPERATURE AND OVERTEMPERATURE
DETECTION
The INT and CT pins have two undertemperature/over-
temperature modes: comparator mode and interrupt mode.
The interrupt mode is the default power-up overtemperature
mode. The INT output pin becomes active when the tempera-
ture is greater than the temperature stored in the T
HIGH
setpoint
register or less than the temperature stored in the T
LOW
setpoint
register. How this pin reacts after this event depends on the
overtemperature mode selected.
Figure 22 illustrates the comparator and interrupt modes for
events exceeding the THIGH limit with both pin polarity settings.
Figure 23 illustrates the comparator and interrupt modes for
events exceeding the T
LOW
limit with both pin polarity settings.
Comparator Mode
In comparator mode, the INT pin returns to its inactive status
when the temperature drops below the THIGH THYST limit or
rises above the TLOW + THYST limit.
Putting the ADT7310 into shutdown mode does not reset the
INT state in comparator mode.
Interrupt Mode
In interrupt mode, the INT pin goes inactive when any ADT7310
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 THIGH setpoint register or less than the temperature
stored in the T
LOW
setpoint register.
Placing the ADT7310 into shutdown mode resets the INT pin
in the interrupt mode.
