Dual-Channel Temperature Monitors and  
Fan-Speed Controllers with Thermistor Inputs  
General Description  
Features  
The MAX6615/MAX6616 monitor two temperature chan-  
nels, either the internal die temperature and the temper-  
ature of an external thermistor, or the temperatures of  
two external thermistors. The temperature data controls  
a PWM output signal to adjust the speed of a cooling  
fan, thereby minimizing noise when the system is run-  
ning cool, but providing maximum cooling when power  
dissipation increases. The fans’ tachometer output sig-  
nals are monitored by the MAX6615/MAX6616 to detect  
fan failure. If a fan failure is detected, the FAN_FAIL  
output is asserted.

Six GPIOs (MAX6616)  
Programmable Fan-Control Characteristics

Unobtrusive Fan-Speed Adjustments  
The 2-wire serial interface accepts standard system  
management bus (SMBusTM) write byte, read byte,  
send byte, and receive byte commands to read the  
temperature data and program the alarm thresholds.  
The programmable alarm output can be used to gener-  
ate interrupts, throttle signals, or overtemperature shut-  
down signals.  
Fail-Safe System Protection  
OT Output for Throttling or Shutdown  
Nine Different Pin-Programmable SMBus  
Addresses  
16-Pin and 24-Pin QSOP Packages  
The MAX6616 features six GPIOs to provide additional  
flexibility. All of the GPIOs power-up as inputs, with the  
exception of GPIO0, which powers up as either an input  
or an output as determined by connecting the PRESET

The MAX6616 is available in a 24-pin QSOP package,  
while the MAX6615 is available in a 16-pin QSOP pack-  
age. Both devices operate from a single-supply voltage  
range of 3.0V to 5.5V, have operating temperature  
ranges of -40°C to +125°C, and consume just 500µA of  
supply current.
