DS1775

Digital Thermometer and Thermostat in SOT23

Thermostat Setpoints Programming

2-WIRE Serial Data Bus

The thermostat registers (T

and T

) can be

The DS1775 supports a bidirectional 2-wire bus and data

transmission protocol. A device that sends data onto the

bus is defined as a transmitter, and a device receiving

data as a receiver. The device that controls the message

is called a “master”. The devices that are controlled by

the master are “slaves”. The bus must be controlled by

a master device which generates the serial clock (SCL),

controls the bus access, and generates the START and

STOP conditions. The DS1775 operates as a slave on

the 2-wire bus. Connections to the bus are made via the

open-drain I/O lines SDA and SCL.

location, and to the 02h location for T

The format of the T

registers is identical to

that of the Thermometer register; that is, 12-bit 2’s com-

plement representation of the temperature in °C. The user

can program the number of bits (9, 10, 11, or 12) for each

chosen the three least significant bits of T and T

are ignored by the thermostat comparator. Table 6 shows

The following bus protocol has been defined

If the user does not wish to take advantage of the ther-

mostat capabilities of the DS1775, the 24 bits can be

used for general storage of system data that need not be

maintained following a power loss.

not busy.

● During data transfer, the data line must remain stable

whenever the clock line is HIGH. Changes in the data

line while the clock line is high are interpreted as con-

trol signals.
