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 V
CC
.
