General description

P3T1085UK is a temperature-to-digital converter with a -40 °C to +125 °C range. It

uses an on-chip band gap temperature sensor and A-to-D conversion technique with

overtemperature detection. The device contains a number of data registers, including

a Configuration register (Conf) to store the device settings (such as device operation

mode), and a temperature register (Temp) to store the digital temp reading, which 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 four target addresses and an alert function which

becomes active when the temperature exceeds the programmed limits.

The I3C interface supports IBI (In Band Interrupt) where P3T1085UK 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. P3T1085UK can be configured for different

operation conditions. It can be set in normal mode to periodically monitor the ambient

temperature, or in shut-down mode to minimize power consumption. The temperature

register always stores a 12 bit two's complement data, giving a temperature resolution of

0.0625 °C
