Temperature Monitors and
PWM Fan Controllers

the highest expected temperature must be greater than
0.25V at 10礎(chǔ), and at the lowest expected tempera-
ture, the forward voltage must be less than 0.95V at
100礎(chǔ). Large power transistors must not be used. Also,
ensure that the base resistance is less than 100&. Tight
specifications for forward current gain (50 < ?<150, for
example) indicate that the manufacturer has good
process controls and that the devices have consistent

BE
characteristics.
Manufacturers of discrete transistors do not normally
specify or guarantee ideality factor. This is normally not
a problem since good-quality discrete transistors tend
to have ideality factors that fall within a relatively narrow
range. We have observed variations in remote tempera-
ture readings of less than ?癈 with a variety of dis-
crete transistors. Still, it is sound design practice to
verify good consistency of temperature readings with
several discrete transistors from any manufacturer
under consideration.
