General Description
The MAX6668/MAX6670 remote-junction thermal
switches with an internal power transistor drive a cool-
ing fan rated for supply voltages up to +12V and
250mA. These devices measure the temperature of an
external P-N junction (typically a diode-connected tran-
sistor) and turn on the fan power switch when the
remote temperature rises above a factory-programmed
threshold. Self-contained and requiring no software
development, the MAX6668/MAX6670 are simple
drop-in fan-control solutions for a variety of systems.
The MAX6670 features an open-drain WARN output
that goes active when the remote temperature exceeds
the factory-programmed fan activation threshold by
+15癈. The MAX6670 features an open-drain OT output
that goes active when the remote temperature exceeds
the factory-programmed threshold by +30癈. The
MAX6668/MAX6670 provide a fan-control input,
FORCEON, that allows the fan to be driven externally,
regardless of temperature.
Available temperature thresholds range from +40癈 to
+75癈 in 5癈 increments. Hysteresis is preset to 8癈 on
the MAX6668 or pin selectable to 4癈, 8癈, or 12癈
using a three-level logic input on the MAX6670.
Temperature threshold accuracy is ?癈 (typ) and
?.2癈 (max) for remote-junction temperatures from
+40癈 to +75癈.
The MAX6668/MAX6670 operate from a +3V to +3.6V
power supply, and are specified over the automotive
temperature range (-40癈 to +125癈). The MAX6668 is
offered in an 8-pin 礛AX package and the MAX6670 is
available in a space-saving 10-pin 礛AX package.
