TC626

1 TC626* * PATENTED TEMPERATURE LIMIT SWITCH FEATURES s s s s s Requires No External Components On-Chip Temperature Sensing TO-220 package for "Hot Spot" Mounting 50mA Output Signal TO-220 Package (TC626VAB) TO-92 Package for Direct Circuit Board Mounting GENERAL DESCRIPTION The TC626 is a temperature limit detector that notifies the system when measured temperature is above the factory-programmed setting. It is designed to replace mechanical (bimetal) temperature limit switches and offers increased ruggedness, higher reliability and greater setpoint accuracy. It requires no external components. The TC626 operates over a – 55°C to +125°C temperature 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. 2 3 4 Range – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C – 55°C to +125°C APPLICATIONS s s s s s Vibration-Immune Temperature Sensing Fan Speed Control Circuits System Overtemperature Shutdown Advanced Thermal Warning Consumer Products SYSTEM OVERTEMPERATURE PROTECTION 5V TO 18V PIN 1 SWITCHES 'HIGH' IF TEMPERATURE GOES ABOVE THE PRESET VALUE.
