PCT2075 datasheet



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.


1. Pin-for-pin replacement for LM75 series but allows up to 27 devices on the bus

2. Power supply range from 2.7 V to 5.5 V

3. Programmable temperature threshold and hysteresis set points during operation



1. System thermal management

2. Personal computers

3. Electronics equipment

4. Industrial controllers
