DS1775R7+T&R

The DS1775R7+T&R from Maxim Integrated Products is a digital thermometer and thermostat in 5 pin SOT-23 package. The digital thermometer and thermostat provides temperature readings that indicate the device's temperature. Thermostat settings and temperature readings are all communicated to/from the DS1775 over a simple 2-wire serial interface and device is truly a temperature to digital converter. For applications that require greater temperature resolution, the user can adjust the readout resolution from 9 to 12bits. This is particularly useful in applications where thermal runaway conditions must be detected quickly. It is software compatible with DS75 2-wire thermal watchdog. Allowing for low cost thermal monitoring/control in space constrained applications. Typical applications include personal computers/servers/workstations, cell phones, office equipment and any thermally-sensitive system.
