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

Stand Alone Thermostat Capability

) 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

• Up to Eight Devices Can Operate on a 2-Wire Bus

● Fast 25ms (max) 9-Bit Conversion Time
