Microchip Technology TCN75
The TCN75 is a serially programmable temperature sensor that notifies the host controller when ambient temperature exceeds a user programmed set point. The INT/CMPTR output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt. This permits reading the current temperature, programming the set point and hysteresis, and configuring the device.| Part No. | TCN75 |
