GENERAL DESCRIPTION
The TC626 is a temperature limit detector that notifies
the system when measured temperature is above the fac-
tory-programmed setting. It is designed to replace mechani-
cal (bimetal) temperature limit switches and offers increased
ruggedness, higher reliability and greater setpoint accuracy.
3 It requires no external components.
The TC626 operates over a – 55°C to +125°C tempera-
ture range. It is available in a TO-92 package, which is ideal
for ambient temperature sensing applications. It is also
available in a TO-220-3 package for heatsink temperature
measurement applications.
