Device Overview

Summary

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).

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
