I2C temperatuur sensor en monitorSolid-State Temperature Sensing: 0.5°C Accuracy (Typ.)
Operates from -55°C to +125°C
Operating Supply Range: 2.7V to 5.5V
Programmable Trip Point and Hysteresis with Power-up Defaults
Standard 2-Wire Serial Interface
Thermal Event Alarm Output Functions as interrupt or Comparator/Thermostat Output
Up to 8 TCN75s may Share the Same Bus
Shutdown Mode for Low Standby Power Consumption
5V Tolerant I/O at VDD = 3V
Dit is de 3,3V versie. Hij is dus geoptimaliseerd voor 3,3V, maar werkt ook bij 5V.
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 comparator for thermostat operation or as a temperature event interrupt. Communication with the TCN75 is accomplished via a two-wire bus that is compatible with industry standard protocols. This permits reading the current temperature, programming the set point and hysteresis, and configuring the device.
