What this sensor delivers
The Maxim Integrated MAX6629MUT-T is a digital local temperature sensor that reports a 12-bit temperature reading over an SPI interface. It is built for environments where the sensor and the monitoring circuit share the same board — think power-supply thermal management, server DIMM temperature tracking, or industrial controller hot-spot monitoring. Accuracy is the headline: ±0.8°C typical at 25°C, with a wider spread of -5°C / +6.5°C across the full -55°C to 125°C local sensing range. That ±0.8°C at room temperature is tight enough for most thermal-throttling and fan-control loops, but the wider tolerance at extremes means you budget for it in a -55°C cold-start scenario. The supply range of 3V to 5.5V lets it run from either a 3.3V or 5V rail without a separate regulator. The shutdown mode drops quiescent current when the system enters standby — useful in battery-backed or energy-conscious designs.
Housed in a 6-pin SOT-23-6 surface-mount package. The Bulk shipping option means it arrives in a tube or tray, not tape-and-reel — confirm your pick-and-place feeder setup if you are ordering for automated assembly; the tape-and-reel variant carries a different ordering code suffix.
