Higher resolutions may be obtained by reading the temperature, and truncating the 0.5°C bit (the LSB)
from the read value. This value is TEMP_READ. The value left in the counter may then be read by
issuing a READ COUNTER command. This value is the count remaining (COUNT_REMAIN) after the
gate period has ceased. By loading the value of the slope accumulator into the count register (using the
READ SLOPE command), this value may then be read, yielding the number of counts per degree C
(COUNT_PER_C) at that temperature. The actual temperature may be then be calculated by the user
using the following:
TEMPERATURE=TEMP_READ-0.25 +

OPERATION–THERMOSTAT CONTROLS
Three thermally triggered outputs, THIGH, TLOW, and TCOM, are provided to allow the DS1620 to be used
as a thermostat, as shown in Figure 3. When the DS1620’s temperature meets or exceeds the value stored
in the high temperature trip register, the output THIGH becomes active (high) and remains active until the
DS1620’s measured temperature becomes less than the stored value in the high temperature register, TH.
The THIGH output can be used to indicate that a high temperature tolerance boundary has been met or
exceeded, or it can be used as part of a closed loop system to activate a cooling system and deactivate it
when the system temperature returns to tolerance.
The TLOW output functions similarly to the THIGH output. When the DS1620’s measured temperature
equals or falls below the value stored in the low temperature register, the TLOW output becomes active.
TLOW remains active until the DS1620’s temperature becomes greater than the value stored in the low
temperature register, TL. The TLOW output can be used to indicate that a low temperature tolerance
boundary has been met or exceeded, or as part of a closed loop system it can be used to activate a heating
system and deactivate it when the system temperature returns to tolerance.
The TCOM output goes high when the measured temperature meets or exceeds TH, and will stay high until
the temperature equals or falls below TL. In this way, any amount of hysteresis can be obtained.
