Texas Instruments lists the LM75BIMX-5 as NRND (Not Recommended for New Designs). Existing production runs can still be sourced against an RFQ through independent distribution channels, but the part should not be dropped into a new board spin without a migration plan.
I²C digital temp sensor — bus integration
It reports temperature over a standard two-wire bus, making it straightforward to hang on a microcontroller's I²C port without an ADC channel.
Accuracy and features — what the numbers mean
Accuracy is ±2°C typical and ±3°C worst-case across the full temperature range. That ±3°C ceiling is the figure to budget for in a thermal-shutdown or fan-control loop — the system must tolerate that uncertainty at the extremes. Built-in features include a programmable temperature limit with an output switch (OS) that asserts when the measured temperature crosses the threshold, plus a shutdown mode that drops the sensor's current draw when temperature monitoring is not needed.
