dBCool Remote Thermal

Monitor and Fan Controller

ADT7467

FEATURES

GENERAL DESCRIPTION

Controls and monitors up to 4 fans

The ADT7467 dBCool® 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.

High and low frequency fan drive signal

1 on-chip and 2 remote temperature sensors

Series resistance cancellation on the remote channel

Extended temperature measurement range, up to 191°C

Dynamic T_MINcontrol mode intelligently optimizes

system acoustics

Automatic fan speed control mode manages system cooling

based on measured temperature

The automatic fan speed control loop optimizes fan speed for a

given temperature. A unique dynamic T_MINcontrol mode

enables the system thermals/acoustics to be intelligently

managed. The effectiveness of the system’s thermal solution can

be monitored using the THERM input. The ADT7467 also

provides critical thermal protection to the system using the

bidirectional THERM pin as an output to prevent system or

component overheating.

Enhanced acoustic mode dramatically reduces user

perception of changing fan speeds
