It digitizes temperature with 11 b resolution and reports readings with a typical accuracy of ±2°C (maximum ±3°C) over the full -55°C to 125°C operating range. The sensor runs from a 1.4 V to 3.6 V supply. Its feature set — one-shot conversion, programmable temperature limit with an open-drain output switch, and shutdown mode — gives firmware control over when and how temperature data is collected and acted upon. ## Accuracy and its impact on thermal trip points The ±2°C typical accuracy (max ±3°C) means a firmware-based over-temperature threshold set at 85°C should be de-rated to guarantee the system never exceeds 85°C at the sensor. For applications that only need a rough thermal warning — fan control, chassis temperature — the ±3°C worst-case is acceptable; for precision battery-charging or optical-module monitoring, a tighter-grade sensor may be needed. ## One-shot conversion and low-power operation The one-shot feature lets the host command a single temperature conversion, then the part returns to shutdown mode. This is the right operating pattern for battery-powered sensors that only need periodic temperature readings — once per minute, once per hour — rather than continuous monitoring. The shutdown mode draws negligible current, preserving battery life between reads. ## Package and board fit Housed in an 8-SOIC package (3.90 mm body width), the TMP75BIDR is a drop-in for standard SOIC-8 footprints. The surface-mount package is compatible with reflow soldering and automated pick-and-place. Tape & Reel and Cut Tape options are available for different volume requirements. ## Lifecycle and sourcing It is RoHS3 compliant.","metaTitle":"TI TMP75BIDR Digital Temperature Sensor, SMBus, 8-SOIC","metaDescription":"TI TMP75BIDR digital local temp sensor, ±2°C accuracy, 1.4V-3.6V supply, SMBus output, 8-SOIC.
