8.4 Device Functional Modes

8.4.1 Continuous-Conversion Mode

Continuous conversion is the default operating mode for the TMP107-Q1. In continuous-conversion mode, the

TMP107-Q1 continuously measures temperature (see Table 6). After each temperature conversion, the

temperature register updates with the conversion result, and the configuration register updates with the alert

flags.

8.4.2 Shutdown Mode

Shutdown mode minimizes power dissipation because the TMP107-Q1 shuts down all of the internal active

circuitry except for those that are required to allow communication with the device. During shutdown mode, all

registers can be read from or written to. To trigger a single temperature conversion in shutdown mode, issue a

one-shot command (see the One-Shot Mode section for more details). When the conversion is complete, the

TMP107-Q1 returns to shutdown mode.

8.4.3 One-Shot Mode

One-shot mode triggers single temperature measurements by writing a 1 to OS (bit 12 in the configuration

register) when the device is in shutdown mode. Following the completion of the single temperature conversion,

the TMP107-Q1 returns to shutdown mode. Reading the OS bit always results in a 0. Use one-shot mode to

achieve the lowest power consumption. For highest power savings and accuracy, do not communicate through

the I/O bus during this mode.
