18 | Description | |
19 | ----------- | |
20 | ||
21 | The Texas Instruments TMP108 implements one temperature sensor. An alert pin | |
22 | can be set when temperatures exceed minimum or maximum values plus or minus a | |
23 | hysteresis value. (This driver does not support interrupts for the alert pin, | |
24 | and the device runs in comparator mode.) | |
25 | ||
26 | The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0 | |
27 | degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The | |
28 | operating temperature has a minimum of -55 C and a maximum of +150 C. | |
29 | Hysteresis values can be set to 0, 1, 2, or 4C. | |
30 | ||
31 | The TMP108 has a programmable update rate that can select between 8, 4, 1, and | |
32 | 0.5 Hz. | |
33 | ||
34 | By default the TMP108 reads the temperature continuously. To conserve power, | |
35 | the TMP108 has a one-shot mode where the device is normally shut-down. When a | |
36 | one shot is requested the temperature is read, the result can be retrieved, | |
37 | and then the device is shut down automatically. (This driver only supports | |
38 | continuous mode.) | |
39 | ||
40 | The driver provides the common sysfs-interface for temperatures (see | |
7ebd8b66 | 41 | Documentation/hwmon/sysfs-interface.rst under Temperatures). |
