MC623

3.0 V, Dual Trip Point

Temperature 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.
