Measurements of Lower-Temperature, Outdoor and Industrial Applications Achieve Greater Accuracy With Microchip‘s MCP990X Multi-Channel Temp Sensor Family
2016-03-28 | ReturnAdvanced features of the MCP990X family include remote diode temperature measurement with resistance error correction that compensates for voltage drops from connectors and long board traces, enabling accurate readings of up to 20 inches away from the IC. Injected system noise from components such as DC-DC converters and backlight inverters is also minimized with a sample-frequency hopping filter, allowing for easier placement and routing. The combination of these features with options for dual, triple and quad temperature monitoring provides for a wider range of measurement opportunities for an entire system with a single IC.
“Extending our thermal-management portfolio to include a focus on colder remote and industrial applications gives us a unique offering in the industry,” said Bryan J. Liddiard, marketing vice president of Microchip’s Mixed-signal and Linear Products Division. “These devices complement system designs for our extensive line of microcontrollers as well, helping to ease development time based on the sensing and processing needs of end products.”
Compact package options that take up less silicon space on the PCB and allow for smaller system solutions and better product design for temperature-critical applications include a 2 x 2 footprint for the MCP9902 dual-channel temperature sensor. The IC is the smallest temperature sensor in Microchip’s portfolio and 33 percent smaller than the company’s previous generation dual temperature sensor. Additionally, a 3 x 3 footprint package is available for the MCP9903 triple and MCP9904 quad temp sensors.
Development Support
Microchip also introduced the MCP9902 Evaluation Board (part # ADM00615) today, to enable development with the MCP9902 low temp sensor. This board is available now for $35.00 from microchipDIRECT (http://www.microchipdirect.com/ProductSearch.aspx?keywords=ADM00615) and any of Microchip’s authorized worldwide distributors.
Pricing and Availability
All three members of the MCP990X are available today for sampling and volume production, starting at $0.46 each in 5,000-unit quantities. The MCP9902 is offered in an 8-pin, 2 x 2 WDFN package. The MCP9903 and MCP9904 are available in a 10-pin, 3 x 3 DFN package.
