STMicroelectronics STTS75M2F SO-8 Digital Temperature Sensor IC

The STTS75M2F uses a standard two-wire I2C (also SMBus compatible) serial interface. It supports clock frequencies up to 400 kHz and has a programmable 7-bit slave address, allowing multiple sensors to share the same bus. The interface requires only the SDA and SCL lines, plus power and ground.

The sensor operates from a wide supply voltage range of 2.7V to 5.5V, making it compatible with both 3.3V and 5V logic systems. It features very low power consumption, with typical supply current in the microamp range during active conversion and nanoamp range in shutdown mode, ideal for battery-powered applications.

The sensor offers high typical accuracy of ±0.5°C. It includes a programmable temperature alert function (T_OVERT) with user-defined hysteresis (T_HYST). When the measured temperature exceeds the programmed threshold, the ALERT pin asserts, which can be configured as an interrupt to the host microcontroller for immediate system response.

Yes, the sensor comes in a compact SO-8 (Small Outline 8-pin) surface-mount package. It is designed for standard reflow soldering processes. For optimal thermal performance and accuracy, follow PCB layout guidelines from the datasheet, particularly regarding thermal vias and isolation from heat-generating components.
