(LM26 without VTEMP output)
Check for Samples: LM26NV FEATURES DESCRIPTION The LM26NV is a precision, single digital-output, lowpower thermostat comprised of an internal reference,
DAC, temperature sensor and comparator. Utilizing
factory programming, it can be manufactured with
different trip points as well as different digital output
functionality. The trip point (TOS) can be preset at the
factory to any temperature in the range of -55В°C to
+110В°C in 1В°C increments. The LM26NV has one
digital output (OS/OS/US/US) and one digital input
(HYST). 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 temperature shutdown event (OS or OS) or
an under temperature shutdown event (US or US).
When preset as an overtemperature shutdown (OS),
it will go LOW to indicate that the die temperature is
over the internally preset TOS and go HIGH when the
temperature goes below (TOS–THYST). Similarly, when
preprogrammed as an undertemperature shutdown
(US) it will go HIGH to indicate that the temperature …
