General Description
The TC623 is a 3V solid-state, programmable temper-
ature sensor designed for use in thermal management
applications. It features dual thermal interrupt outputs
(LOW LIMIT and HIGH LIMIT) each of which are set
with an 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 temper-
ature equals the HIGH LIMIT set point and turned off
when temperature falls below the LOW LIMIT set point.
The CONTROL output can be used to provide simple
ON/OFF control to a cooling fan if so desired.
Low voltage operation, easy set point programming,
small size and low cost make the TC623 an ideal
choice for many thermal management applications.
