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 ha...
