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.
