Temperature Sensors - Thermostats - Solid State

Temperature sensors are devices that use electrical methods to measure and control the temperature of an item or environment. Thermostats are temperature-controlled switches that use sensors to detect temperature and then respond by opening or closing a switch based on the detected temperature. Solid state thermostats are electronic thermostats that enable more precise temperature control than traditional thermostats, and are often used for applications with tight temperature tolerances.The Texas Instruments SM72480SD-125/NOPB is a solid state thermostat specifically designed for temperature sensing and control in consumer and automotive electronic applications. It has both low-temperature sensing and normal-operating-temperature sensing, runs on either a 6V battery or 7 to 18V supply, and provides a wide temperature range, adjustable hysteresis, and an open-collector/drain output. This integrated circuit is contained in a small, low-power 6-pin, NR/SO Package with a Maximum Operating Junction Temperature of 125° C.The SM72480SD-125/NOPB is an ideal choice for applications that require temperature control in extreme temperatures and under a variety of operating conditions. It is highly reliable and requires fewer components than other thermostats. Additionally, it is able to detect a temperature change in just 20 milliseconds.The SM72480SD-125/NOPB is designed with two stages of temperature control to adjust the hysteresis. The low-temperature sensing operates between -40° and -50° C and the normal-operating-temperature sensing operates between 5° and 125° C. When the detected temperature reaches the threshold value for one of the stages, the output will go to an active state, either high or low. When the temperature returns to its normal value, the output will go to its inactive state.The SM72480SD-125/NOPB also includes an open-collector/drain output for connection to a load circuit. This output is capable of driving up to 15mA of current directly, or up to 40mA when buffered. This output also has an on-resistance of 0.4 ohms and a propagation delay of 20 microseconds.In addition to temperature sensing and control, the SM72480SD-125/NOPB offers many other features and advantages that make it a good choice for temperature sensing applications. It has a temperature accuracy of ±2°C and a temperature resolution of 1°C. It also supports multiple operating modes, such as cycle-by-cycle enabling, time delay, scalable setpoint monitoring, and hysteretic control. Furthermore, it is RoHS compliant.To summarize, the Texas Instruments SM72480SD-125/NOPB is a solid state thermostat that provides reliable temperature sensing and control in extreme temperature ranges and under varying operating conditions. It enables precise temperature control with a 0.2°C accuracy, 1°C resolution, and a 20 millisecond response time. Additionally, it supports multiple operating modes and is RoHS compliant. It is an ideal choice for a variety of consumer and automotive electronic applications that require highly accurate temperature control.
