DS1775  
Digital Thermometer and Thermostat in SOT23  
General Description  
Benefits and Features  
Temperature Measurements Require No External  
The DS1775 digital thermometer and thermostat  
provides temperature readings that indicate the device’s  
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.  
Components  
Measures Temperatures from -55°C to +125°C  
(-67°F to +257°F)  
±2.0°C Thermometer Accuracy  
Thermometer Resolution is Configurable from 9 Bits  
to 12 Bits (0.5°C to 0.0625°C Resolution)  
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.  
User-Definable Thermostat Settings  
Data is Read From/Written to Through a  
2-Wire Serial Interface  
The open-drain thermal alarm output, O.S., becomes  
active when the temperature of the device exceeds a  
2.7V to 5.5V Wide Power-Supply Range  
Software Compatible with DS75 2-Wire Thermal  
user-defined temperature T . The number of consecutive  
OS  
Watchdog in Thermometer Mode  
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.  
Space-Conscious 5-Pin SOT23 Package with Low  
Thermal Time Constant  
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.  
Ordering Information appears at end of data sheet.  
Applications  
Personal Computers/Servers/Workstations  
Cell Phones  
● Office Equipment  
Any Thermally-Sensitive System
