General Description
The MAX6650/MAX6651 fan controllers use an
SMBus/I2C-compatible interface to regulate and mon-
itor the speed of 5VDC/12VDC brushless fans with built-in
tachometers. They automatically force the fan’s tachome-
ter frequency (fan speed) to match a preprogrammed
value in the Fan-Speed Register by using an external
MOSFET or bipolar transistor to linearly regulate the volt-
age across the fan. The MAX6650 regulates the speed of
a single fan by monitoring its tachometer output. The
MAX6651 also regulates the speed of a single fan, but it
contains additional tachometer inputs to monitor up to four
fans and control them as a single unit when they are used
in parallel.
The MAX6650/MAX6651 provide general-purpose
input/output (GPIO) pins that serve as digital inputs,
digital outputs, or various hardware interfaces. Capable
of sinking 10mA, these open-drain inputs/outputs can
drive an LED. To add additional hardware control, con-
figure GPIO1 to fully turn on the fan in case of software
failure. To generate an interrupt when a fault condition
is detected, configure GPIO0 to behave as an active-
low alert output. Synchronize multiple devices by set-
ting GPIO2 (MAX6651 only) as an internal clock output
or an external clock input.
The MAX6650 is available in a space-saving 10-pin
MAX package, and the MAX6651 is available in a
small 16-pin QSOP package.
