MAX31827 is a low-power temperature switch with I2C interface. The device is a ±1°C accuracy from -40°C to +125°C (12 bits) local temperature switch and sensor with I2C/SM- Bus interface. The combination of small 6-bump wafer-lev- el package (WLP) and high accuracy makes this temper- ature sensor/switch ideal for a wide range of applications.
