Product Description
Product Overview
The TCN75 is a serially programmable temperature sensor designed to notify a host controller when ambient temperature exceeds a user-defined set point. It offers programmable hysteresis and features a standard 2-wire serial interface. The INT/CMPTR output can function as an interrupt or a comparator/thermostat, and up to eight TCN75 devices can share the same bus. Its low power consumption, small size, and ease of use make it suitable for various thermal management and protection applications in electronic systems.
