P3T1755DPZ

P3T1755DPZ is an I3C, I²C-bus interface, 0.5°C accuracy, digital temperature sensor. It uses an on-chip band gap temperature sensor and an A-to-D conversion technique with 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 12.5MHz) and I²C (up to 3.4MHz) interface. The I²C interface supports up to 32 target addresses and an alert function that becomes active when the temperature exceeds the programmed limits. The I3C interface supports IBI (In Band Interrupt) where P3T1755 emits its address into the arbitrated address header on the I3C bus to notify the controller of an interrupt. It does not require an additional interrupt pin. The application includes IoT, portable devices, SSD, industrial controllers, servers, and PC/Notebook.
