Product Summary

The TC6293 is a programmable logic output temperature detector designed for use in thermal management applications. The TC6293 features an on-board temperature sensor, while the TC6293 connects to an external NTC thermistor for remote sensing applications. Both devices feature dual thermal interrupt outputs (HIGH LIMIT and LOW LIMIT), each of which program with a single external resistor. The applications of the TC6293 include Power Supply Overtemperature Detection, Consumer Equipment, Temperature Regulators, CPU Thermal Protection.
