DESCRIPTION

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 ±2°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.

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

A block diagram of the DS75LV is shown in Figure 1

and detailed pin descriptions are given in Table 1.
