TC6501/02-1 1/17/00
Ultra Small Temperature Switch
with Pin-Selectable Hysteresis
leads onto the die. Pin 2 of the 5-Pin SOT-23A package
provides the lowest thermal resistance to the die.
Thus,
place the TC6501 and TC6502 closest to the device being
monitored and use a short wide coppertrace from pin 2 to the
device. In some cases, the 5-Pin SOT-23A package can be
placed directly under the socketed
P for the improved
thermal contact.
APPLICATIONS
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 had by designing in 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)
