3C Accurate, Factory Preset Thermostat
General Description
The LM26 is a precision, single digital-output, low-power
thermostat comprised of an internal reference, DAC, tem-
perature sensor and comparator. Utilizing factory program-
ming, it can be manufactured with different trip points as well
as different digital output functionality. The trip point (T
)
can be preset at the factory to any temperature in the range
of 55C to +110C in 1C increments. The LM26 has one
digital output (OS/OS/US/US), one digital input (HYST) and
one analog output (V
TEMP
). The digital output stage can be
preset as either open-drain or push-pull. In addition, it can be
factory programmed to be active HIGH or LOW. The digital
output can be factory programmed to indicate an over tem-
perature shutdown event (OS or OS) or an under tempera-
ture shutdown event (US or US). When preset as an over-
temperature shutdown (OS) it will go LOW to indicate that
the die temperature is over the internally preset T
OS
and go
HIGH when the temperature goes below (T
–T
). Simi-
larly, when preprogrammed as an undertemperature shut-
down (US) it will go HIGH to indicate that the temperature is
below T
US
and go LOW when the temperature is above
(T
+T
). The typical hysteresis, T
, can be set to
2C or 10C and is controlled by the state of the HYST pin. A
V
analog output provides a voltage that is proportional
to temperature and has a 10.82mV/C output slope.
Available parts are detailed in the ordering information. For
other part options, contact a National Semiconductor Dis-
tributor or Sales Representative for information on minimum
order qualification. The LM26 is currently available in a
5-lead SOT-23 package.
