General Description
The MAX6665 is a fully integrated thermal switch with
an internal power transistor for driving a cooling fan
rated up to 24V and 250mA. When the MAX6665’s tem-
perature rises above a factory-programmed threshold,
the
FANOUT
pin becomes active and powers the fan.
The MAX6665 is available with factory-programmed fan
activation threshold temperatures from +40°C to +70°C
in 5°C increments. Accuracy of the fan activation trip
point is ±1°C (typ) and ±3°C (max). The trip point’s hys-
teresis is pin selectable to 1°C, 4°C, or 8°C. Two open-
drain logic outputs indicate overtemperature con-
ditions:
WARN
is activated when the temperature is
15°C above the fan activation threshold, and
OT
is acti-
vated when the temperature is 30°C above the thresh-
old. These features can be used to safely power down
systems that are overheated.
The MAX6665 operates from a +2.7V to +5.5V power
supply, and the associated fan can be powered from
4.5V to 24V. It is available in an 8-pin SO package and
operates from -40°C to +125°C.
