    Check for Samples: LM27 FEATURES DESCRIPTION The LM27 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 +120В°C to
    +150В°C in 1В°C increments. The LM27 has one digital
    output (OS/OS/US/US), one digital input (HYST) and
    one analog output (VTEMP). 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 is below TUS ...
