Product details

12-bit I²C temp sensor in a 1.6 mm² footprint

The TMP112BIDRLR is a digital local temperature sensor from TI's TMP112BI series, delivering 12-bit resolution over a 2-wire I²C/SMBus interface.

Typical accuracy is ±0.5°C from 0°C to 65°C, with a worst-case ±1°C across the full -40°C to 125°C range. That ±0.5°C window is tight enough for thermal-throttle logic in a base station or battery-pack monitoring without a calibration step. Supply voltage spans 1.4V to 3.6V, so it runs directly off a 1.8V or 3.3V rail — no extra LDO needed.

SOT-563 footprint — board-fit note

The supplier device package is SOT-5X3, a 5-lead SOT-563 measuring roughly 1.6 mm x 1.6 mm. The 0.5 mm pitch and exposed pad demand a standard 2-layer PCB with a thermal via under the pad if the sensor is near a heat source. Cut Tape works for prototypes and small runs.

Frequently asked questions

Is TMP112BIDRLR equivalent to TMP112AIDRLR?

Both are in the TMP112 family with the same 12-bit I²C interface and SOT-563 package. The B-grade variant offers ±0.5°C typical accuracy versus the A-grade's ±1°C — check your system's temperature error budget before substituting.

Can TMP112BIDRLR operate at 1.8V?

Yes — the supply range of 1.4V to 3.6V includes 1.8V. The I²C bus voltage must match the supply rail or use level-shifting if the host MCU runs at a different voltage.
