Overview

The MIC280 is a digital thermal supervisor capable of measuring its own internal temperature and that of a remote PN junction. The remote junction may be an inexpensive commodity transistor (e.g., 2N3906) or an embedded thermal diode such as those found in Intel Pentium® II/III/IV CPUs, AMD Athlon® CPUs, and Xilinx Virtex® FPGAs.

  • Measures Local and Remote Temperature
  • Highly Accurate Remote Sensing: ±1°C max., +60°C to +100°C
  • Superior Noise Immunity for Reduced Temperature Guardbands
  • 9-bit to 12-bit Temperature Resolution for Remote Zone
  • Fault Queues to Further Reduce Nuisance Tripping
  • Programmable High, Low, and Overtemperature Thresholds for Each Zone
  • SMBus 2.0-Compatible Serial Interface Including Device Timeout to Prevent Bus Lockup
  • Voltage-Tolerant I/Os
  • Open-Drain Interrupt Output Pin Supports SMBus Alert Response Address Protocol
  • Low Power Shutdown Mode
