O.S. OUTPUT TRANSFER FUNCTION Figure 2

Regardless of the mode chosen, the O.S. output is open–drain and the active state is set in the

configuration register. The power–up default is active low. Refer to the “OPERATION–Programming”

section for instructions in adjusting the thermostat setpoints, thermostat mode, and O.S. active state.

OPERATION–Programming

There are three areas of interest in programming the DS1775: the configuration register, the T_OSregister,

and the T_HYSTregister. All programming is done via the 2–wire interface by setting the pointer to the

appropriate location. Table 3 illustrates the pointer settings for the four registers of the DS1775.

T_OS

The DS1775 will power up with the temperature register selected. If the host wishes to change the data

pointer it simply addresses the DS1775 in the write mode (R/ W =0), receives an acknowledge, and writes

the 8 bits that correspond to the new desired location. The last pointer location is always maintained so

that consecutive reads from the same register do not require the host to always provide a pointer address.

The only exception is at power–up, in which case the pointer will always be set to 00h, the temperature
