9.1 Application Information

The TMP75B-Q1 is used to measure the PCB temperature where the device is mounted. The programmable address options allow up to eight locations on the board to be monitored on a single serial bus. Connecting the ALERT pins together and programming the temperature limit registers to desired values allows for a temperature watchdog operation of all devices, interrupting the host controller only if the temperature exceeds the limits.
