P3T1755 I3C, I2C-bus interface, 0.5 °C accuracy, digital temperature sensor Rev. 1.2 — 15 July 2024 Product data sheet 1 General description The P3T1755 is a temperature-to-digital converter from -40 °C to +125 °C range. It uses an on-chip band gap temperature sensor and A-to-D conversion technique with an overtemperature detection. The device contains a number of configuration and data registers to store the device settings, such as device operation mode, and a temperature register (Temp) to store the digital temp reading that can be communicated by a controller via the 2-wire serial I3C (up to 12.5 MHz) and I2C (up to 3.4 MHz) interface. The I2C interface supports up to 32 target addresses and an alert function which becomes active when the temperature exceeds the programmed limits.
