Descriptions:

The DS1621S+T&R is a digital thermometer and thermostat that provides accurate temperature measurements with user-programmable trip points (TH and TL). It communicates via an I²C interface, making it suitable for integration into microcontroller-based systems. The device can operate autonomously as a thermostat or be controlled by a host processor.

Features:

• Digital Temperature Sensing: Eliminates the need for external calibration.
• User-Configurable Resolution: 9-bit to 12-bit selectable.
• Nonvolatile Storage: Saves temperature settings during power loss.
• Programmable Thermostat: Supports independent high (TH) and low (TL) trip points.
• Wide Supply Voltage Range: Compatible with 3V and 5V systems.
• Compact Package: 8-pin SOIC for space-constrained applications.
• Low Power Consumption: Ideal for battery-powered systems.

This device is commonly used in industrial controls, consumer electronics, and environmental monitoring applications.
