Temperature Comparison
and Interrupt System
At the end of each conversion cycle, the converted
temperature data are compared to various set-point
thresholds to control the INT, THERM, SDL, and SDR
outputs. All temperature threshold limits are stored in
the threshold limit registers (Table 6) and can be
changed through the SMBus digital interface.
THERM is an active-low thermal-overload output indicat-
ing that the THERM overtemperature set point is exceed-
ed. With the THERM threshold set to an appropriate value,
the THERM output can be used to control clock throttling.
When this pin is pulled low by an external signal, a status
bit (bit 7, status register 2) is set, and the fan speed is
unconditionally forced to full-on speed. The only way to
reset the status bit is to read status register 2. Connect a
10k
pullup resistor between THERM and VCC.
