The TC623 is a 3V 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 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 temperature equals the HIGH LIMIT set point and turned off …
