DS7505  
Digital Thermometer and Thermostat  
General Description  
Benefits and Features  
Extends Performance Range with a Low-Voltage,  
The DS7505 low-voltage (1.7V to 3.7V) digital thermom-  
eter and thermostat provides 9-, 10-, 11-, or 12-bit digital  
temperature readings over a -55°C to +125°C range with  
±0.5°C accuracy over a -0°C to +70°C range. A 9-bit reso-  
lution mode is software compatible with the LM75.  
1.7V to 3.7V Operating Range  
Maximizes System Accuracy in Broad Range of  
Thermal Management Applications  
• Measures Temperature from -55°C to +125°C  
(-67°F to +257°F)  
• ±0.5°C Accuracy Over a 0°C to +70°C Range  
User-Configurable Resolution from 9 Bits (Default)  
to 12 Bits (0.5°C to 0.0625°C Resolution)  
The DS7505 thermostat has a dedicated open-drain  
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 thermo-  
Reduces Cost with No External Components and  
stat operation based on user-defined trip points (T  
and  
OS

) that are stored in EEPROM registers.

Increases Reliability and System Robustness  
• Internally Filtered Data Lines for Noise Immunity  
(50ns Deglitch)  
Applications  
Networking Equipment  
Cellular Base Stations  
● Office Equipment  
• Bus Timeout Feature Prevents Lockup on a 2-Wire  
Interface  
Simplifies Distributed Temperature-Sensing  
Applications with Multidrop Capability  
Medical Equipment  
Any Thermally Sensitive System
