The EMC1046 is a System Management Bus (SMBus) temperature sensor designed to monitor up to five external diodes and one internal diode with ±1°C accuracy for external diodes and ±2°C accuracy for the internal diode. It features Resistance Error Correction for up to 100 Ω of series resistance, Beta Compensation for BJT or transistor model diodes, and 0.125°C resolution. The device operates from a 3.3 V supply and supports up to a 2.2 nF filter capacitor. It is housed in a 10-pin TSSOP package and is lead-free and RoHS compliant.
The EMC1046/EMC1047 are high accuracy, low cost, System Management Bus (SMBus) 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).
