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 MAX6665s 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癈 to +70癈
in 5癈 increments. Accuracy of the fan activation trip
point is ?癈 (typ) and ?癈 (max). The trip points hys-
teresis is pin selectable to 1癈, 4癈, or 8癈. Two open-
drain logic outputs indicate overtemperature con-
ditions: WARN is activated when the temperature is
15癈 above the fan activation threshold, and OT is acti-
vated when the temperature is 30癈 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癈 to +125癈.
