Key Featrues
Wide Temperature Range: The DS1621S operates effectively from -55°C to +125°C, making it suitable for extreme environments such as industrial, automotive, and outdoor applications. This broad range ensures reliable performance in both high and low-temperature conditions, enhancing its versatility across various use cases.
High Accuracy: With an accuracy of ±0.5°C within the 0°C to 70°C range and ±2°C across the full temperature range, the DS1621S provides precise temperature measurements. This high accuracy is critical for applications requiring tight temperature control, such as medical devices and test measurement systems.
Nonvolatile Memory: The DS1621S stores user-defined temperature settings in nonvolatile memory, allowing the device to retain configurations even when powered off. This feature eliminates the need for reprogramming after power cycles, improving system efficiency and reliability.
Simple 2-Wire Interface: The device communicates via a 2-wire (I2C) serial interface, simplifying integration with microcontrollers and other digital systems. This reduces design complexity and minimizes the number of required components, saving both space and cost.
Thermostatic Control: The DS1621S includes a programmable thermostat function with user-defined high (TH) and low (TL) temperature thresholds. This enables automatic temperature monitoring and control, making it ideal for applications like thermal management in networking equipment and personal computing devices.
