General Description
The DS7505 low-voltage (1.7V to 3.7V) digital ther-
mometer and thermostat provides 9-, 10-, 11-, or 12-bit
digital temperature readings over a -55癈 to +125癈
range with ?.5癈 accuracy over a -0癈 to +70癈 range.
A 9-bit resolution mode is software compatible with the
LM75. Communication with the DS7505 is achieved
through a simple 2-wire serial interface. Three address
pins allow up to eight DS7505 devices to operate on the
same 2-wire bus, which greatly simplifies distributed
temperature-sensing applications.
The DS7505 thermostat has a dedicated open-drain out-
put (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
) that are stored in EEPROM registers.
