The MC623 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 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.

CASE TBD  
Low voltage operation, easy setpoint programming, small size and  
low cost make the MC623 an ideal choice for many thermal  
management applications.
