Temperature switches

Smart sensors for autonomous thermal measurement and protection

TI offers a variety of temperature switches with programmability options from factory reset to pin or resistor compatibility. These small, accurate temperature switches provide thermal protection and monitoring.

Temperature switches

Temperature switches are smart sensors that autonomously make decisions providing real-time thermal protection without interrupting the control processing system.
