TCN75AVOA

Product Summary

Description:Microchip Technology Inc.’s TCN75A digital temperature sensor converts temperatures between -40°C and +125°C to a digital word, with ±1°C (typical) accuracy.
The TCN75A product comes with user-programmable registers that provide flexibility for temperature-sensing applications. The register settings allow
user-selectable, 0.5°C to 0.0625°C temperature measurement resolution, configuration of the power-saving Shutdown and One-shot (single
conversion on command while in Shutdown) modes and the specification of both temperature alert output and hysteresis limits. When the temperature changes
beyond the specified limits, the TCN75A outputs an alert signal. The user has the option of setting the alert output signal polarity as an active-low or active-high comparator output for thermostat operation, or as temperature event interrupt output for microprocessor-based systems.
This sensor has an industry standard 2-wire, I2C? compatible serial interface, allowing up to eight devices to be controlled in a single serial bus. These features
make the TCN75A ideal for low-cost, sophisticated multi-zone temperature-monitoring applications
