Part Number : PCT2075
Function : I2C-bus Fm+, 1 degree C accuracy, digital temperature sensor and thermal watchdog
Manufacturers : NXP Semiconductors.
The PCT2075 is a temperature-to-digital converter featuring +-1’C accuracy over 25’C to +100’C range. It uses an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique with an overtemperature detection output that is a drop-in replacement for other LM75 series thermal sensors.
The device contains a number of data registers: Configuration register (Conf) to store the device settings such as device operation mode, OS operation mode, OS polarity and OS fault queue; temperature register (Temp) to store the digital temp reading, set-point registers (Tos and Thyst) to store programmable overtemperature shutdown and hysteresis limits, and programmable temperature sensor sampling timeTidle, that can be communicated by a controller via the 2-wire serial I2C-bus Fast-mode Plus interface.
