Product details

Active lifecycle and BOM-fit for a ±1.5°C digital local sensor

The LM77CIMX-5/NOPB: Its 9-bit resolution delivers temperature readings in 0.5°C steps — granular enough for thermal monitoring in industrial control, power-supply feedback, or enclosure management, where sub-degree precision is not required.

I²C interface and supply rail integration

The LM77CIMX-5/NOPB communicates over a standard I²C bus, which simplifies connection to most microcontrollers and SoCs — the SDA and SCL lines pull up to the same 3V to 5.5V supply rail the sensor uses, so no level translator is needed when the host runs at 3.3V or 5V.

Package and board-level handling for the 8-SOIC footprint

Available in Tape & Reel (TR) and Cut Tape (CT) options, the part suits both high-volume pick-and-place assembly and prototype or low-volume builds.

Output switch and programmable limit for system-level control

The integrated output switch and programmable limit allow the sensor to assert an interrupt or control signal when the temperature crosses a user-set threshold — useful for overtemperature shutdown in power supplies or fan-control triggers without polling the I²C bus continuously. Shutdown mode reduces power consumption when the sensor is not actively measuring, which matters in battery-backed or thermally constrained designs.

Compliance and regulatory status for global BOMs

The LM77CIMX-5/NOPB is ROHS3 compliant, meeting the current European Union restriction on hazardous substances for electronic equipment. Texas Instruments lists the part as active, so no end-of-life notice or last-time-buy is pending — the supply channel remains open through authorized and independent distribution.

Frequently asked questions

What is the accuracy of the LM77CIMX-5/NOPB across its temperature range?

The wider tolerance at the extremes should be budgeted into the system thermal design.

What package does the LM77CIMX-5/NOPB come in?

The LM77CIMX-5/NOPB is supplied in an 8-SOIC package (0.154" width, 3.90mm body), with the supplier device package also listed as 8-SOIC. It is available in Tape & Reel (TR) and Cut Tape (CT) options.
