DS1631U+

DS1631U+ is a high-precision digital thermometer and thermostat. The thermostat on this device provides custom hysteresis with user-defined trip points (TH and TL). The TH and TL registers and thermometer configuration settings are stored in NV EEPROM so they can be programmed prior to installation. Applications include network routers and switches, cellular base stations, portable products, and any space-constrained thermally sensitive product.

• Maximize system accuracy in broad range of thermal management applications
• Reduce cost with no external components
• Simplify distributed temperature-sensing applications with multidrop capability
• Up to eight devices can operate on a 2-wire bus
• Flexible and non-volatile user-defined thermostatic modes with custom hysteresis
• Supply voltage range from 2.7 to 5.5V
• Thermometer error is ±0.5°C max at 0°C to +70°C, 3.0V ≤ VDD ≤ 5.5V
• Standby supply current is 800nA max at 0°C to +70°C
• 8-pin µSOP package
• Operating temperature range from -55°C to +125°C
