Product details

What this sensor delivers

The Texas Instruments TMP117MAIYBGR is a digital, local temperature sensor that reads temperature over an I²C/SMBus interface with 16-bit resolution. Its typical accuracy is ±0.1°C across the 0°C to 85°C range, with a guaranteed maximum of ±0.2°C. Built-in features include standby mode, shutdown mode, a one-shot conversion trigger, and programmable temperature limits. The one-shot is useful in battery-powered designs where you want a reading on demand and then let the part sleep. The programmable limit can drive an alert pin without the host polling the bus continuously.

The package is a 6-bump DSBGA measuring 1.49 mm x 0.95 mm. That is a very small footprint — it saves board area but requires a controlled solder-paste stencil and good alignment during reflow. Mounting is surface mount only. If you are doing a prototype run, the Cut Tape option avoids committing to a full reel.

That means it is safe to qualify into a new design and there is no LTB window to track.

Frequently asked questions

What is the accuracy of TMP117MAIYBGR?

Typical accuracy is ±0.1°C over the 0°C to 85°C range, with a guaranteed maximum of ±0.2°C. This is measured under the test condition of 30°C to 45°C (0°C to 85°C).

What voltage does TMP117MAIYBGR operate at?

The supply voltage range is 1.8V to 5.5V. It is compatible with both 1.8V and 3.3V logic rails without an external level shifter.

What is the interface of TMP117MAIYBGR?

The output interface is I²C/SMBus. The part acts as a slave on the bus; the host reads the 16-bit temperature register over the standard two-wire protocol.

Is TMP117MAIYBGR obsolete or End-of-Life?

No. The lifecycle status is Active (current production). There is no NRND or EOL notice for this variant, so it is suitable for new designs and production ramps.

Is TMP117MAIYBGR compatible with 3.3V?

Yes. The supply voltage range of 1.8V to 5.5V includes 3.3V. The I²C bus logic levels are referenced to VCC, so at 3.3V supply the SDA/SCL pins are 3.3V-compatible.
