| Description |
| ----------- |
| |
| The Texas Instruments TMP108 implements one temperature sensor. An alert pin |
| can be set when temperatures exceed minimum or maximum values plus or minus a |
| hysteresis value. (This driver does not support interrupts for the alert pin, |
| and the device runs in comparator mode.) |
| |
| The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0 |
| degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The |
| operating temperature has a minimum of -55 C and a maximum of +150 C. |
| Hysteresis values can be set to 0, 1, 2, or 4C. |
| |
| The TMP108 has a programmable update rate that can select between 8, 4, 1, and |
| 0.5 Hz. |
| |
| By default the TMP108 reads the temperature continuously. To conserve power, |
| the TMP108 has a one-shot mode where the device is normally shut-down. When a |
| one shot is requested the temperature is read, the result can be retrieved, |
| and then the device is shut down automatically. (This driver only supports |
| continuous mode.) |
| |
| The driver provides the common sysfs-interface for temperatures (see |
| Documentation/hwmon/sysfs-interface.rst under Temperatures). |
