PCT2202UK: Ultra low power, 1.8 V, 1 deg. C accuracy, digital temperature sensor with I2C-bus interface

The PCT2202 is an I²C-bus, serial output temperature sensor available in a tiny WLCSP6 package. Requiring no external components, the PCT2202 is capable of reading temperatures at 12-bit resolution or 0.0625 °C with an accuracy of ±0.5 °C from 0 °C to 85 °C.

The PCT2202 features SMBus and I²C-bus interface compatibility including HSM (High-Speed Mode: 3.4 MHz), and allows up to four devices on one bus. It also features an SMB alert function.

The PCT2202 is ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications. The device is specified for operation over a temperature range of ‑40 °C to +125 °C and a voltage range of 1.65 V to 1.95 V.
