XC31B series are ultra small CMOS temperature sensor ICs. As a bandgap type temperature sensor is built-into the XC31B, linearity, in comparison to thermistor type temperature sensors, is much better. The operating temperature range of the series is from -30℃ to +80℃. The XC31B comes in a mini molded SOT-25 and USP-6B packages with a supply current of only 7μA (@VOUT=2.0V) and as such, is suitable for use with various portable devices. Output voltage is selectable in 0.1V increments within a range of 2.0V to 6.0V (at 25℃).
The XC31B Series is an ultra‑small CMOS temperature sensor IC designed for portable devices. It offers a selectable output voltage from 2.0 V to 6.0 V in 0.1 V steps and operates over a temperature range of –30 °C to +80 °C.
The device is supplied in SOT‑25 and USP‑6B packages with a low supply current of about 7 µA. Detailed electrical characteristics, typical performance curves, and packaging information are provided for designers.
