The maximum power dissipation of the TMP814PWR is 1.5W. However, it's essential to consider the thermal resistance and ambient temperature to ensure the device operates within the recommended temperature range.
To configure the TMP814PWR for remote temperature sensing, connect the DQ (data output) pin to a microcontroller or other digital device. Then, use the TMP814PWR's internal diode or an external diode to sense the remote temperature. The TMP814PWR will convert the temperature data to a digital signal, which can be read by the microcontroller.
The TMP814PWR has an accuracy of ±1°C (max) over the operating temperature range of -20°C to 100°C. However, this accuracy can be affected by factors such as thermal resistance, self-heating, and noise.
While the TMP814PWR can operate up to 150°C, it's not recommended for high-temperature applications above 125°C due to reduced accuracy and potential device degradation. For high-temperature applications, consider using a more specialized temperature sensor like the TMP116 or TMP117.
The TMP814PWR's POR and BOR features ensure the device resets correctly during power-up and brown-out conditions. To handle these features, ensure the power supply is stable and within the recommended voltage range (2.7V to 5.5V). Also, consider adding external circuitry to filter out noise and ensure a clean power-up sequence.
