General description
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.
