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 under Temperatures). |
