Device Overview

Summary

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).

Additional Features
    • Supports diodes requiring the BJT or transistor model
    • Resistance Error Correction (up to 100 Ohms)
    • Up to six External Temperature Monitors
      • ±1°C Accuracy (60°C < TDIODE < 100°C)
      • 0.125°C Resolution
      • Supports up to 2.2nF filter capacitor
      • Anti-parallel diodes for extra diode support and compact design
    • Internal Temperature Monitor
      • ±2°C accuracy
    • 3.3V Supply Voltage
    • Available in 10 pin TSSOP RoHS Compliant package
