LM94 - Hardware Monitor

Datasheet Summary

Description

The LM94 hardware monitor has a two wire digital interface compatible with SMBus 2.0.

Using a ΣΔ ADC, the LM94 measures the temperature of four remote diode connected transistors as well as its own die and 16 power supply voltages.

Features

  • 8-bit ΣΔ ADC.
  • Monitors 16 Power Supplies.
  • Monitors 4 Remote Thermal Diodes and 2 LM60.
  • New TruTherm Technology Support for Precision Thermal Diode Measurements.
  • Internal Ambient Temperature Sensing.
  • Programmable Autonomous Fan Control Based on Temperature Readings with Fan Boost Support.
  • Fan Boost Support on Tachometer Limit Error Event.
  • Fan Control Based on 13-step Lookup Table or PI Control Loop or Combination of Both.
