MAX6642ATT98+ Information

General Description

The MAX6642 precise, two-channel digital temperature sensor accurately measures the temperature of its own die and a remote PN junction and reports the temperature data over a 2-wire serial interface. The remote PN junction is typically a substrate PNP transistor on the die of a CPU, ASIC, GPU, or FPGA. The remote PN junction can also be a discrete diode-connected small-signal transistor.

Key Features

  • Integrated Temperature Sensor Enables Simultaneous Dual Temperature (Remote and Local) Measurements
    • Remote Accuracy ±1°C
    • Local Accuracy ±2°C from +60°C to +100°C
    • Measures Remote Temperature up to +150°C
    • 0.25°C Resolution
  • Dual Zone Monitoring Automates Over-Temperature Alarms
    • Programmable Remote/Local Temperature Thresholds
    • ALERT Output
  • Small Footprint
    • 3mm x 3mm TDFN Package with Exposed Pad
    • Low Thermal Mass Reduces Measurement Latency
    • SMBus/I2C Address Hardwired

Application

  • Desktop Computers
  • Graphic Cards
  • Notebook Computers
  • Servers
  • Test and Measurement Equipment
  • Thin Clients
  • Workstations
