DS1726U+

The DS1726U+ is a high precision 3-wire digital thermometer and thermostat in 8 pin µSOP package. It provides temperature measurement and stand-alone thermostat capability over a -55°C to +125°C range. The resolution of the measured temperature is user selectable from 9bits to 12bits. Communication with IC is achieved through a 3-wire serial bus. It offers thermostatic functionality with three dedicated thermostat outputs (THIGH, TLOW and TCOM), overtemperature (TH) and undertemperature (TL) user-programmable thresholds stored in on-chip EEPROM. For stand-alone thermostat operation, TH and TL can be programmed prior to installation and the device can be configured to automatically begin taking temperature measurements at power-up. This device is used in thermostatic controls and thermally sensitive applications.
