GENERAL DESCRIPTION
The TC623 is a 3V solid-state, programmable tempera-
ture sensor designed for use in thermal management appli-
cations. 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 equals
the user-programmed limits. The CONTROL output is driven
active (high) when temperature equals 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 TC623 an ideal choice for
many thermal management applications.
