- Kernel driver tmp108
- ====================
- Supported chips:
- * Texas Instruments TMP108
- Prefix: 'tmp108'
- Addresses scanned: none
- Datasheet: https://www.ti.com/product/tmp108

- 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).
