The Microchip EMC1812 is a 2 channel temperature sensor features Rate of Change (ROC), Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/transistor model), and Ideality Configuration combine to provide a robust solution for complex environmental monitoring applications. This 2-Wire (I2C compatible),high accuracy sensor a pre-emptive system alert and another protective measurement layer to catch and manage variable system temperatures. It operates on voltage range of 1.62V to 3.6V.Temperature sensor resolution (Internal/External) of 0.125°C Configurable alert pinsAdjustable SMBus addressAuto-Beta Compensation, Configurable Ideality Factor, Hottest Diode Compare, Resistance Error CorrectionExtended temperature range between -40°C and +125°C8-Lead Very, Very Thin Plastic Dual Flat, No Lead – 2 x 2 mm Body(WDFN) package
