1mA, and the output voltage is guaranteed to be less than
0.3V, then an additional 0.3mW of power is dissipated within
the IC. This corresponds to a 0.042
°C rise in die tempera-
ture in the 5-Pin SOT-23A.
Temperature monitoring accuracy depends on the ther-
mal 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 TC6501 through TC6504 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 TC6501 and TC6503 have open drain outputs and
are therefore intended to interface as microprocessor reset
inputs. 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 TC6502 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 TC6502 with a higher temperature threshold to alert
the user of an impending thermal shutdown, should the
temperature continue to rise. (See Figure 2)
The TC6504 with its push/pull output could be used in a
similar fashion to turn on a heater element at cold tempera-
tures. (See Figure 3)
