General Description
The MAX6661 is a remote temperature sensor and fan-
speed regulator that provides complete closed-loop fan
control. The remote temperature sensor is typically a
common-collector PNP, such as a substrate PNP of a
microprocessor, or a diode-connected transistor, typi-
cally a low-cost, easily mounted 2N3904 NPN type or
2N3906 PNP type.
The device also incorporates a closed-loop fan con-
troller that regulates fan speed with tachometer feed-
back. The MAX6661 compares temperature data to a
fan threshold temperature and gain setting, both pro-
grammed over the SPI" bus by the user. The result is
automatic fan control that is proportional to the remote-
junction temperature. The temperature feedback loop
can be broken at any time for system control over the
speed of the fan.
Fan speed is voltage controlled as opposed to PWM
controlled, greatly reducing acoustic noise and maxi-
mizing fan reliability. An on-chip power device drives
fans rated up to 250mA.
Temperature data is updated every 500ms and is read-
able at any time over the SPI interface. The MAX6661 is
accurate to 1癈 (max) when the remote junction is
between +60癈 to +100癈. Data is formatted as a 10-
bit + sign word with 0.125癈 resolution.
The MAX6661 is specified between -40癈 to +125癈
and is available in a 16-pin QSOP package.
