DESCRIPTION
The DS75 digital thermometer and thermostat provides 9, 10, 11, or 12-bit digital temperature readings
over a -55癈 to +125癈 range with ?癈 accuracy over a -25癈 to +100癈 range. At power-up, the
DS75 defaults to 9-bit resolution for software compatibility with the LM75. Communication with the
DS75 is achieved via a simple 2wire serial interface. Three address pins allow up to eight DS75 devices
to operate on the same 2wire bus, which greatly simplifies distributed temperature sensing applications.
The DS75 thermostat has a dedicated opendrain output (O.S.) and programmable fault tolerance, which
allows the user to define the number of consecutive error conditions that must occur before O.S is
activated. There are two thermostatic operating modes that control thermostat operation based on user-
defined trip-points (T
OS
and T
HYST
).
A block diagram of the DS75 is shown in Figure 1 and detailed pin descriptions are given in Table 2.
