Remote-Junction Temperature-Controlled

Fan-Speed Regulator with SMBus Interface

General Description

Features

♦ Integrated Thermal Sensing and Fan-Regulation

The MAX6660 is a remote temperature sensor and fan-

speed regulator that provides a complete fan-control

solution. The remote temperature sensor is typically a

common-collector PNP, such as a substrate PNP of a

microprocessor, or a diode-connected transistor, typi-

cally a low-cost, easily mounted 2N3904 NPN type or

2N3906 PNP type.

Solution

♦ Programmable Fan Threshold Temperature

♦ Programmable Temperature Range for Full-Scale

Fan Speed

♦ Accurate Closed-Loop Fan-Speed Regulation

♦ On-Chip Power Device Drives Fans Rated

The device also incorporates a closed-loop fan con-

troller that regulates fan speed with tachometer feed-

back. The MAX6660 compares temperature data to a

fan threshold temperature and gain setting, both pro-

grammed over the SMBus™ by the user. The result is

automatic fan control that is proportional to the remote-

junction temperature. The temperature feedback loop

can be broken at any time for system control over the

speed of the fan.

Up to 250mA

♦ Programmable Under/Overtemperature Alarms

♦ SMBus 2-Wire Serial Interface with Timeout

(Cannot “Lock Up” the SMBus)

♦ Supports SMBus Alert Response

♦ ACPI Compatible, Including OVERT System

Shutdown Function

♦ ±±1C (ꢀ+01C to ꢀ±001C) Thermal-Sensing Accuracy

♦ MAX+++0EVKIT Available

Fan speed is voltage controlled as opposed to PWM

controlled, greatly reducing acoustic noise and maxi-

mizing fan reliability. An on-chip power device drives

fans rated up to 250mA.

Ordering Information

Temperature data is updated every 0.25s and is read-

able at any time over the SMBus interface. The

MAX6660 is accurate to 1°C (max) when the remote

junction is between +60°C to +100°C. Data is formatted

as a 10-bit + sign word with 0.125°C resolution.
