2-Channel Temperature Monitor with Dual Automatic

PWM Fan-Speed Controller and Five GPIOs

General Description

Features

The MAX6678 monitors its own temperature and the

temperatures of two external diode-connected transis-

tors, which typically reside on the die of a CPU or other

integrated circuit. The device reports temperature values

in digital form using a 2-wire serial interface. The

MAX6678 provides a programmable alarm output to gen-

erate interrupts, throttle signals, or overtemperature shut-

down signals.

♦ Two Thermal-Diode Inputs

♦ Local Temperature Sensor

♦ Five GPIO Input/Outputs

♦ Two PWM Outputs for Fan Drive (Open Drain; May

Be Pulled Up to +5V)

♦ Programmable Fan-Control Characteristics

♦ Automatic Fan Spin-Up Ensures Fan Start

The 2-wire serial interface accepts standard System

Management Bus (SMBus)^™write byte, read byte, send

byte, and receive byte commands to read the tempera-

ture data and program the alarm thresholds. The tem-

perature data controls a PWM output signal to adjust

the speed of a cooling fan, thereby minimizing noise

when the system is running cool, but providing maxi-

mum cooling when power dissipation increases.

♦ Controlled Rate of Change Ensures Unobtrusive

Fan-Speed Adjustments

♦ 1°C Remote Temperature Accuracy (+60°C to

+145°C)

♦ Temperature Monitoring Begins at POR for Fail-

Five GPIO pins provide additional flexibility. The GPIO

power-up states are set by connecting the GPIO preset

Safe System Protection

♦ OT Output for Throttling or Shutdown

inputs to ground or V

♦ Four Versions Available, Each with a Different

The MAX6678 is available in a 20-pin QSOP package

and a 5mm x 5mm thin QFN package. It operates from

3.0V to 5.5V and consumes just 500µA of supply current.
