Shutdown Mode

Shutdown mode of the TMP112A device allows the user to conserve power by shutting down all device

circuitry except the serial interface, thereby reducing the current of the TMP112A to less than 0.5µA (typical

value). Shutdown mode is initiated when the SD bit in the configuration register is set to 1; after confi-

guring the registers in this way, the TMP112A will shut down after completing the current conversion. To exit

shutdown mode, write SD bit to 0, the TMP112A will re-enter continuous conversion mode.
