MIC280 Datasheet Precision Ittybitty Thermal Supervisor

Manufacturer: Microchip Technology

Overview: MIC280 Precision IttyBitty Thermal Supervisor.

General Description

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 modity 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.

A 2-wire SMBus® 2.0-patible serial interface is provided for host munication.

Key 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 Overtemperature Thresholds for Each Zone.
  • SMBus 2.0-Compatible Serial Interface Including Device Timeout to Prevent Bus Lockup.
  • Voltag.
