8 Application and Implementation

8.1 Application Information

The TMP75C is used to measure the PCB temperature of the location it 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.
