Overview

The ADT7467 controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or power sensitive applications requiring active system cooling. The ADT7467 can drive a fan using either a low or high frequency drive signal, monitor the temperature of up to two remote sensor diodes plus its own internal temperature, and measure and control the speed of up to four fans so that they operate at the lowest possible speed for minimum acoustic noise.

  • Thermal Management

  • Notebook and Desktop Computers
  • Game Consoles
  • RFID Readers

  • Controls and monitors up to 4 fans
  • High and low frequency fan drive signal
  • 1 on-chip and 2 remote temperature sensors
  • Series resistance cancellation on the remote channel
  • Extended temp measurement range, up to 191°C
  • Dynamic TMIN control mode optimizes system acoustics intelligently
  • Automatic fan speed control mode controls system cooling based on measured temperature
  • Enhanced acoustic mode dramatically reduces user perception of changing fan speeds
  • Thermal protection feature via THERM output
  • Thermal control circuit via THERM input

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
