Temperature monitoring accuracy depends on the
thermal resistance between the device being monitored and
the temperature switch die. Heat flows primarily through
the leads onto the die. Pin 2 provides the lowest thermal
resistance to the die. To achieve the best temperature
monitoring results, the MAX6501 and MAX6502 should
be placed closest to the device being monitored. In
addition, a short and wide copper trace from Pin 2 to the
device should be used. In some cases, the 5–Pin SOT–23A
package can be placed directly under the socketed
microprocessor for improved thermal contact.
APPLICATIONS
The MAX6501 has an open drain output and is therefore
intended to interface as a microprocessor reset input.
Moreover, the combination of these two devices can be used
to implement a temperature window alarm by wire–ORing the
outputs and using an external pull up resistor. (See Figure 1)

The MAX6502 can be used to control a DC fan. The fan
turns on when the sensed temperature rises above the factory
set threshold and remains on until the temperature falls
below threshold minus the hysteresis selected. An additional
fail safe measure could be designed by using a second
MAX6502 with a higher temperature threshold to alert the
user of an impending thermal shutdown, should the
temperature continue to rise. (See Figure 2)
