2-Channel Temperature Monitor with Dual

Automatic PWM Fan-Speed Controller

MAX640

General Description

Features

The MAX6640 monitors its own temperature and one

external diode-connected transistor or the temperatures

of two external diode-connected transistors, typically

available in CPUs, FPGAs, or GPUs. The 2-wire serial

interface accepts standard System Management Bus

(SMBus^TM) write byte, read byte, send byte, and

receive byte commands to read the temperature data

and program the alarm thresholds. Temperature data

can be read at any time over the SMBus, and three pro-

grammable alarm outputs can be used to generate

interrupts, throttle signals, or overtemperature shut-

down signals.

♦ Two Thermal-Diode Inputs

♦ Local Temperature Sensor

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

+100°C)

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

be Pulled Up to +13.5V)

♦ Programmable Fan-Control Characteristics

♦ Automatic Fan Spin-Up Ensures Fan Start

♦ Controlled Rate-of-Change Ensures Unobtrusive

Fan-Speed Adjustments

The temperature data is also used by the internal dual

PWM fan-speed controller to adjust the speed of up to

two cooling fans, thereby minimizing noise when the

system is running cool, but providing maximum cooling

when power dissipation increases. Speed control is

accomplished by tachometer feedback from the fan, so

that the speed of the fan is controlled, not just the PWM

duty cycle. Accuracy of speed measurement is 4ꢀ.

♦ ±±4 Fan-Speed Measurement Accuracy

♦ Temperature Monitoring Begins at POR for Fail-

Safe System Protection

♦ OT and THERM Outputs for Throttling or

Shutdown

♦ Measures Temperatures Up to +150°C

♦ Tiny 5mm x 5mm 16-Pin TQFN and QSOP

The MAX6640 is available in 16-pin QSOP and 16-pin

TQFN 5mm x 5mm packages. It operates from 3.0V to

3.6V and consumes just 500μA of supply current.
