Microchip announces the MCP9808 silicon temperature sensor, which serves a broad range of applications by guaranteeing high accuracy of 0.5 degrees from -20 to +100 degrees Celsius, combined with high temperature resolution of 12 bits (0.0625 degrees Celsius/LSB). The MCP9808 comes in small MSOP and 2x3 mm DFN 8-pin packages, for space-constrained applications, and additional features include shutdown, an under/over-temperature monitor and a critical-temperature alert.
The combination of one of the industry’s highest accuracy silicon temperature sensors with the MCP9808’s wide range of features provides the flexibility for designers to optimise systems for high accuracy over a wide range of temperatures. 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.
In addition, many applications can benefit from reduced energy consumption via accurate temperature monitoring and control that enables more efficient operation. With its shutdown and temperature monitoring/alert features, the MCP9808 can help to adjust the real-time power utilisation of applications ranging from residential HVAC systems to industrial equipment. Specifically, its 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 optimisation. Finally, the MCP9808’s critical-temperature alert can increase the system’s life by preventing harmful operating temperatures.
The MCP9808 is available today for samples and volume production, in 8-pin MSOP and 2x3 mm DFN packages.
