The EMC1047 is a high-accuracy SMBus temperature sensor designed for monitoring up to six external diode channels and one internal diode. It provides ±1°C accuracy for external diode temperatures between 60°C and 100°C and ±2°C accuracy for the internal diode. The device features Resistance Error Correction up to 100 ohms, automatic Beta Compensation for BJT or transistor model diodes, and an Anti-parallel diode support architecture for compact design. It supports a 0.125°C resolution, operates on a 3.3V supply, and includes a 'Hottest Of' thermal zone comparison function. The part is housed in a 10-pin TSSOP package and is lead-free and RoHS compliant.
The EMC1046/EMC1047 are high accuracy, low cost, SMBus / I2C temperature sensors. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to CPU diodes requiring the BJT or transistor model) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications.
Each device provides ±1° accuracy for external diode temperatures and ±2°C accuracy for the internal diode temperature. The EMC1046/EMC1047 monitors up to seven temperature channels (up to six external and one internal).
