GENERAL DESCRIPTION
The TC622 and TC624 are programmable solid state
temperature switches designed to replace mechanical
switches in sensing and control applications. Both devices
integrate the temperature sensor along with a voltage refer-
ence 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 compared to the
programmed setpoint. The OUT and OUT outputs are
driven to their active state when the measured temperature
exceeds the programmed setpoint.

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.
