Thermostat Control
In its comparator operating mode, the DS1775 functions as a thermostat with programmable hysteresis, as
shown in Figure 2. When the DS1775s temperature meets or exceeds the value stored in the high
temperature trip register (T
OS
) a consecutive number of times, as defined by the configuration register, the
output becomes active and stays active until the first time that the temperature falls below the temperature
stored in the low temperature trigger register (T
HYST
). In this way, any amount of hysteresis may be
obtained. The DS1775 powers up in the comparator mode with T
OS
= +80癈 and T
HYST
= +75癈 and can
be used as a stand-alone thermostat (no 2-wire interface required) with those setpoints.
In the interrupt mode, the O.S. output first becomes active following the programmed number of
consecutive conversions above T
OS
. The fault can only be cleared by either setting the DS1775 in a
shutdown mode or by reading any register (temperature, configuration, T
OS
, or T
HYST
) on the device.
Following a clear, a subsequent fault can only occur if consecutive conversions fall below T
HYST
. This
interrupt/clear process is thus cyclical (T
OS
, clear, T
HYST
, clear, T
OS
, clear, T
HYST
, clear, etc.). Only the
first of multiple consecutive T
OS
violations activates O.S., even if each fault is separated by a clearing
function. The same situation applies to multiple consecutive T
HYST
events.
