Fan Controller and Remote Temperature Sensor

with SMBus Serial Interface

General Description

Features

The MAX1669 fan controller includes a precise digital

thermometer that reports the temperature of a remote

sensor. The remote sensor is a diode-connected transis-

tor—typically a low-cost, easily mounted 2N3906 PNP

type—replacing conventional thermistors or thermocou-

ples. Remote accuracy is 3ꢀ° for transistors from multi-

ple manufacturers, with no calibration needed. The

MAX1669 has an independent fan controller with a low-

current logic output requiring external power compo-

nents to interface to a D° brushless fan. The fan

controller has two modes of operation: a low-frequency

(20Hz to 160Hz) PWM mode intended for driving the fan

motor, or a high-impedance DA° output that generates

a variable D° control voltage. In PWM mode, the FAN

frequency can be synchronized to an external clock.

ꢀ No Calibration Required

ꢀ 20Hz to 160Hz PWM Output for Fan

ꢀ PWM Frequency Sync Input (260kHz)

ꢀ Flexible Fan Interface: Linear or PWM

ꢀ SMBus 2-Wire Serial Interface

ꢀ Programmable Under/Overtemperature Alarms

ꢀ ALERT Latched Interrupt Output

ꢀ OVERT Thermostat Output

ꢀ Two GPIO Pins

ꢀ Write-Once Configuration Protection

ꢀ Supports SMBus Alert Response

Other key features include general-purpose inputs/out-

puts (GPIOs) for fan presence detection and a thermo-

stat output intended as a fan override signal in case the

host system loses the ability to communicate. The inter-

nal AD° has a wide input voltage range and gives

overrange readings when too large an input voltage is

applied. Other error-checking includes temperature

out-of-range indication and diode open/short faults.

ꢀ ±±3C Temperature Accuracy (-ꢀ03C to ꢁ12ꢂ3Cꢃ

remote)

ꢀ ±µA Standby Supply Current

ꢀ ꢁ±V to ꢁꢂ.ꢂV Supply Range

ꢀ Small 16-Pin QSOP Package

The MAX1669 is available in a space-saving 16-pin

QSOP package that allows it to fit adjacent to the

SLOT1 connector.
