Remote Temperature Switches with Integrated

Fan Controller/Driver

General Description

Features

The MAX6668/MAX6670 remote-junction thermal

switches with an internal power transistor drive a cool-

ing fan rated for supply voltages up to +12V and

250mA. These devices measure the temperature of an

external P-N junction (typically a diode-connected tran-

sistor) and turn on the fan power switch when the

remote temperature rises above a factory-programmed

threshold. Self-contained and requiring no software

development, the MAX6668/MAX6670 are simple

“drop-in” fan-control solutions for a variety of systems.

ꢀ +12V, 250mA Integrated Fan Driver

ꢀ No Calibration Required

ꢀ Pin-Selectable 4°C, 8°C, or 12°C Hysteresis

(MAX6670)

ꢀ Factory-Programmed Temperature Thresholds

from +40°C to +75°C

ꢀ Overtemperature Warning Signals

ꢀ 110µA (typ) Supply Current

The MAX6670 features an open-drain WARN output

that goes active when the remote temperature exceeds

the factory-programmed fan activation threshold by

+15°C. The MAX6670 features an open-drain OT output

that goes active when the remote temperature exceeds

the factory-programmed threshold by +30°C. The

MAX6668/MAX6670 provide a fan-control input,

FORCEON, that allows the fan to be driven externally,

regardless of temperature.

Available temperature thresholds range from +40°C to

+75°C in 5°C increments. Hysteresis is preset to 8°C on

the MAX6668 or pin selectable to 4°C, 8°C, or 12°C

using a three-level logic input on the MAX6670.

Temperature threshold accuracy is 1°C (typ) and

2.2°C (max) for remote-junction temperatures from

+40°C to +75°C.

8 µMAX

The MAX6668/MAX6670 operate from a +3V to +3.6V

power supply, and are specified over the automotive

temperature range (-40°C to +125°C). The MAX6668 is

offered in an 8-pin µMAX package and the MAX6670 is

available in a space-saving 10-pin µMAX package.
