TC622 TC624 LOW COST, SINGLE TRIP POINT TEMPERATURE SENSOR Features s s s s Temperature Set Point Easily Programs with a Single External Resistor Operates with 2.7V Power Supply (TC624) TO-220 Package for Direct Mounting to Heatsink (TC622x AT) or Standard 8-Pin PDIP and SOIC Cost Effective The TC622 has a power supply voltage range of 4.5V to 18.0V while the TC624 operates over a power supply range of 2.7V to 4.5V. Both devices are usable over a temperature range of - 40°C to +125°C (TC622Vxx, TC624Vxx). Both devices feature low supply current making them suitable for many portable applications. Eight-pin through-hole and surface mount packages are available. The TC622 is also offered in a 5-pin TO-220 package.

Both devices integrate the temperature sensor along with a voltage reference and all required detector circuitry to form a stand-alone temperature switch. The desired temperature set point is set by the user with a single external resistor. Ambient temperature is sensed and pared to the programmed setpoint. The OUT and OUT outputs are driven to their active state when the measured temperature exceeds the programmed setpoint.
