DESCRIPTION

The DS75 2–wire thermal watchdog provides 9–bit temperature readings which indicate the temperature

of the device. Thermostat settings and temperature readings are all communicated to/from the DS75 over

a simple 2–wire serial interface. No additional components are required; the device is truly a

“temperature–to–digital” converter.

The DS75 has three address bits that allow a user to multidrop up to eight sensors along the 2–wire bus,

greatly simplifying the bussing of distributed temperature sensing networks.

The open–drain thermal alarm output, O.S., becomes active when the temperature of the device exceeds a

user–defined temperature T_OS. The number of consecutive faults required to set O.S. active is

configurable by the user. The device can also be configured in the interrupt or comparator mode, to

customize the method which clears the fault condition.

For applications that require greater temperature resolution, the user can adjust the readout resolution

from 9 to 12 bits. This is particularly useful in applications where thermal runaway conditions must be

detected quickly.
