TCN75 Overview
The TCN75 is a serially programmable temperature sensor that notifies the host controller when ambient temperature exceeds a user programmed set point. Hysteresis is also programmable. The INT/CMPTR output is programmable as either a simple parator for thermostat operation or as a temperature event interrupt.
