Microchip Technology’s MCP9808 silicon temperature sensor can serve a broad range of applications as it guarantees high accuracy of 0.5 degrees from -20°C to 100°C, along with high temperature resolution of 12 bits. It is in a small MSOP and 2×3 mm DFN 8-pin packages. Additional features include shutdown, and under/over-temperature monitor and a critical-temperature alert.

The combination of the MCP9808’s wide range of features with one of the industry’s highest accuracy silicon temperature sensors makes applications with high accuracy over a wide range of temperatures possible. These applications include thermostats operating at -20 to +45°C, personal computers operating at +85°C and industrial or automotive applications which have an operating temperature of up to +125°C.

Accurate temperature monitoring and control enables more efficient operation make many applications benefit from reduced energy consumption. The MCP9808 can help to adjust the real-time power utilization of applications ranging from residential HVAC systems to industrial equipment with its shutdown and temperature monitoring/alert features. The shutdown feature reduces power consumption in both line- and battery-powered systems. The on-chip over/under temperature monitor can improve system performance through thermal optimization. The MCP9808’s critical-temperature can increase the system’s life by preventing harmful operating temperatures.

For temperature sensing applications, the MCP9808 has user-programmable registers which enable user-selectable settings include shutdown and low-power modes and the specification of temperature Event and Critical output boundaries. The user has the option of setting the event output signal polarity as an active-low or active-high comparator output for microprocessor-based systems.
