In many systems, temperature control is fundamental. There are a number of passive and active temperature sensors that can be used to measure system temperature, including: thermocouple, resistive temperature detector, thermistor and silicon temperature sensors. These sensors provide temperature feedback to the system controller to make decisions such as, over-temperature shutdown, turn-on/off cooling fan, temperature compensation or general purpose temperature monitor. Microchip offers a broad portfolio of thermal management products, including Logic Output, Voltage Output and Serial Output Temperature Sensors. These products allow the system designer to implement the device that best meets their application requirements. Key features include high accuracy, low power, extended temperature range and small packages. In addition, Microchip’s linear products can be used to support Thermocouple, RTD and Thermistor applications.
