SMBus and I²C Digital Temperature Sensor

• The SMBus and I²C Digital Temperature Sensor is a digital temperature sensor with high-accuracy, low-power, and NTC/PTC thermistor replacements.

• The Temperature Sensor provides ≤±0.5°C temperature accuracy with good temperature linearity over the normal operating range of -40°C to +125°C. It can provide extended temperature measurement mode, extending the temperature measurement range from -55°C to +150°C.

• The rated working voltage range of the sensor is 1.4V~5.5V DC, and the maximum quiescent current in the entire working rage is 10µA (temperature measurement frequency 4Hz). The on-chip 12-bit ADC offers resolutions down to 0.0625°C.

• The digital temperature sensor adopts SOT563 / DFNWB package of 1.6mm×1.6mm, is compatible with SMBus and I² interface, and allows up to four devices on one bus. The device also features an SMBus alert function.

• The SMBus and I²C digital temperature sensor can be used for extended temperature measurement in communication, computer, consumer electronics, environmental, industrial and instrumentation applications.

·Soldering Recommendations: When mounting the sensor, use a reflow soldering profile suitable for small-form-factor packages to avoid thermal damage and ensure electrical connectivity.

·ESD Protection: Always follow electrostatic discharge (ESD) safe handling procedures during installation to prevent damage to the integrated circuit.

·I²C Address Configuration: Verify the address selection pins (if available) to prevent address conflicts when using multiple sensors on the same bus.

·Thermal Design Consideration: Keep the sensor away from heat-generating components (e.g., processors, power regulators) to avoid measurement inaccuracies caused by localized heating.

·Storage Conditions: Store the sensor in a dry, anti-static environment at room temperature until ready for use to preserve long-term performance.
