3.0 V, Dual Trip Point Temperature Sensor
MC623
3.0 V , Dual Trip Point emperature Sensor
The MC623 is a 3.0 V solid-state, programmable temperature
sensor designed for use in thermal management applications. It
features dual thermal interrupt outputs (LOW LIMIT and HIGH
LIMIT) each of which program with a single external resistor. The
HIGH LIMIT and LOW LIMIT outputs are driven active (high) when
measured temperature exceeds the user-programmed limits. The
CONTROL output is driven active (high) when temperature exceeds
the HIGH LIMIT setpoint, and turned off when temperature falls
below the LOW LIMIT setpoint. The CONTROL output can be used
to provide simple ON/OFF control to a cooling fan if so desired.
Low voltage operation, easy setpoint programming, small size and
low cost make the MC623 an ideal choice for many thermal
management applications.
