Overview

The LM77 is a digital temperature sensor and thermal window comparator with an I2C™ Serial Bus interface. The window-comparator architecture of the LM77 eases the design of temperature control systems conforming to the ACPI (Advanced Configuration and Power Interface) specification for personal computers.

  • Window comparison simplifies design of ACPI compatible temperature monitoring and control.
  • Serial Bus interface
  • Separate open-drain outputs for Interrupt and Critical Temperature shutdown
  • Shutdown mode to minimize power consumption
  • Up to 4 LM77s can be connected to a single bus
  • 9-bit + sign output; full-scale reading of over 128˚C Key Specifications
  • Supply Volt
