Temperature switches

Achieve autonomous temperature protection with configurable ALERT thresholds

parametric-filterView all products
Monitor one or two temperature thresholds and send high/low digital output directly to a microcontroller GPIO or the enable-pin on a power supply for automatic protection of a system with our temperature switch portfolio. Our configurable temperature switches help minimize production costs with self-test capabilities, allow systems to be protected autonomously with integrated, selectable hysteresis for enhanced noise immunity, and reduce system size up to 50% versus discrete implementations.
