Features & Applications

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 found in Intel Pentium* II/III/IV CPUs, AMD Athlon* CPUs, and Xilinx Virtex* FPGA's. A 2-wire SMBus* 2.0 compatible serial interface is provided for host communication. Remote temperature is measured with ±1°C accuracy and 9-bit to 12-bit resolution (programmable). Independent high, low, and over-temperature thresholds are provided for each zone.

Features :

  • 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 over-temperature thresholds for each zone
  • SMBus 2 compatible serial interface including device timeout to prevent bus lockup
  • Voltage tolerant I/O’s
  • Open-drain interrupt output pin - supports SMBus Alert Response Address protocol
  • Low power shutdown mode
  • Locking of critical functions to insure failsafe operation
  • Failsafe response to diode faults
  • Enables ACPI compliant thermal management
  • 3.0 V to 3.6 V power supply range
  • IttyBitty™ SOT23-6 package

Applications :

  • Desktop, server and notebook computers
  • Printers and copiers
  • Test and measurement equipment
  • Thermal supervision of Xilinx Virtex FPGA's
  • Wireless/RF systems
  • Intelligent power supplies
  • Datacom/telecom cards
