dBCOOL^™Remote Thermal

ControllerandFanController

ADT7460^*

FEATURES

GENERAL DESCRIPTION

Controls and Monitors up to 4 Fan Speeds

1 On-Chip and 2 Remote Temperature Sensors

Dynamic T_MINControl 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

The ADT7460 dBCOOL controller is a thermal monitor and

multiple PWM fan controller for noise-sensitive applications

requiring active system cooling. It can monitor the temperature

of up to two remote sensor diodes, plus its own internal tem-

perature. It can measure and control the speed of up to four

fans so that they operate at the lowest possible speed for mini-

mum acoustic noise. 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 ADT7460 also provides critical Thermal Protection to the

system using the bidirectional THERM pin as an output to

prevent system or component overheating.
