GENERAL DESCRIPTION
The DS1775 digital thermometer and thermostat
provides temperature readings that indicate the
devices temperature. Thermostat settings and
temperature readings are all communicated
to/from the DS1775 over a simple 2-wire serial
interface. No additional components are
required; the device is truly a temperature-to-
digital converter.
For applications that require greater temperature
resolution, the user can adjust the readout
resolution from 9 to 12 bits. This is particularly
useful in applications where thermal runaway
conditions must be detected quickly.
The open-drain thermal alarm output, O.S.,
becomes active when the temperature of the
device exceeds a user-defined temperature T
OS
.
The number of consecutive faults required to set
O.S. active is configurable by the user. The
device can also be configured in the interrupt or
comparator mode, to customize the method
which clears the fault condition.
As a digital thermometer, the DS1775 is
software compatible with the DS75 2-wire
thermal watchdog. The DS1775 is assembled in
a compact 5-pin SOT23 package, allowing for
low-cost thermal monitoring/control in space-
constrained applications. The low thermal mass
allows for time constants previously only
possible with thermistors.
