Digital Thermometer and Thermostat

DESCRIPTION

FEATURES

This low-voltage (1.7V to 3.7V) digital thermometer

and thermostat provides 9-, 10-, 11-, or 12-bit digital

temperature readings over a -55°C to +125°C range

with M2°C accuracy over a -25°C to +100°C range. At

power-up, the DS75LV defaults to 9-bit resolution for

software compatibility with the LM75. Communication

with the DS75LV is achieved through a simple 2-wire

serial interface. Three address pins allow up to eight

DS75LV devices to operate on the same 2-wire bus,

which greatly simplifies distributed temperature-

sensing applications.

Cꢀ Operating Range from 1.7V to 3.7V

Cꢀ Temperature Measurements Require No

External Components

Cꢀ Measures Temperatures from -55°C to +125°C

(-67°F to +257°F)

Cꢀ M2°C Accuracy Over a -25°C to +100°C Range

Cꢀ Thermometer Resolution is User-

Configurable from 9 (Default) to 12 Bits (0.5°C

to 0.0625°C Resolution)

Cꢀ 9-Bit Conversion Time is 25ms (Max)

Cꢀ Thermostatic Settings are User-Definable

Cꢀ Data Read/Write Occurs Through a 2-Wire

Serial Interface (SDA and SCL Pins)

Cꢀ Data Lines Filtered Internally for Noise

Immunity (50ns Deglitch)

The DS75LV 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 thermostat operation

based on user-defined trip-points (T_OSand T_HYST).

Cꢀ Bus Timeout Feature Prevents Lockup

Problems on 2-Wire Interface

Cꢀ Multidrop Capability Simplifies Distributed

Temperature-Sensing Applications

Cꢀ Pin/Software Compatible with the LM75

Cꢀ Available in 8-Pin ꢀSOP (ꢀMAX) and SO

Packages

A block diagram of the DS75LV is shown in Figure 1

and detailed pin descriptions are given in Table 2.
