Product details

Features that matter for low-power and alert designs

The TMP100MDBVREP includes a shutdown mode and standby mode for reducing supply current between measurements — useful in battery-powered or energy-harvesting nodes. The one-shot feature lets the host trigger a single conversion and then return the sensor to standby, minimizing average current. An output switch (open-drain alert pin) can be programmed to assert when the temperature exceeds a set limit, offloading the host from continuous polling.

Package and mounting — SOT-23-6 footprint

The part comes in a 6-lead SOT-23 surface-mount package. The SOT-23-6 footprint is compact and fits dense PCBs where board area is tight.

Frequently asked questions

Does TMP100MDBVREP support shutdown mode?

Yes, the part includes a shutdown mode and standby mode for reducing power consumption between conversions, plus a one-shot feature for single-trigger measurements.

Is TMP100MDBVREP compatible with 3.3V logic?

Yes, the supply voltage range of 2.7V to 5.5V covers 3.3V and 5V logic rails directly, so no level shifting is needed for the I²C/SMBus interface.

How does TMP100MDBVREP compare to TMP101?

The TMP101 adds an SMBus Alert (ALERT) pin with programmable temperature limits and hysteresis, while the TMP100 relies on the output switch for alert functionality. Both share the same SOT-23-6 footprint, 11-bit resolution, and ±2°C accuracy — the TMP101 is the choice if you need a dedicated SMBus-compatible alert pin for host interrupt.
