DESCRIPTION
The AMC6821 is an intelligent temperature monitor
and pulse-width modulation(PWM)fan controller.It is
designed for noise-sensitive orpower-sensitive
applications that require active systemcooling.Using
either a low-frequency orahigh-frequency PWM
signal, this device can simultaneously drive a fan,
monitorremote sensordiodetemperatures.and
measure and control the fan speed so that it operates
with minimal acoustic noise at the lowest possible
speed.
The AMC6821 has three fan controlmodes:Auto
Temperature-Fan mode,Software-RPM mode,and
Software-DcY mode. Each mode controls the fan
speed by changing the duty cycle of a PWM outout.
Auto Temperature Fan mode isanintelligent
closed-loop control thatoptimizes fanspeed
according to user-defined parameters. This mode
allows the AMC6821 to run as a stand-alone device
without cPU intervention; the fan can continue to be
controlled based ontemperature measurements
even if the cPu or system locks up.Software-RPM
mode is a second closed-loop control.In this mode
the AMC6821 adjusts the PWM output to maintain a
consistent fan speed at a user-speciried target value
that is. the device functions as a fan speed requlator
Software-RPM mode can also be used toallow the
AMC6821 to operate as a stand-alone device.The
third mode.
Software-DCYisopen-loop.In
Software-DcY mode, the PwM duty cycle isset
directly by the value written to the device.
The AMC6821 has a programmable SMBALERT
output to indicate error conditions and a dedicated
FAN-FAULT outout to indicate fan failure.The
THERM pin is a fail-safe output forover-temperature
conditions that can be used to throttle a CPU clock
Additionally.
the
OVR
pin indicates
the
over-temperature limit as well. All ofthe alarm
thresholds are set through the device registers.The
AMC6821 is available in a osoP-16 package.
