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
OS
and T
HYST
).
A block diagram of the DS75LV is shown in Figure 1
and detailed pin descriptions are given in Table 2.
