|   | Kernel driver lm77 | ||
|  | ================== | ||
|  | 
 | ||
|  | Supported chips: | ||
|  |   * National Semiconductor LM77 | ||
|  |     Prefix: 'lm77' | ||
|  |     Addresses scanned: I2C 0x48 - 0x4b | ||
|  |     Datasheet: Publicly available at the National Semiconductor website | ||
|  |                http://www.national.com/ | ||

|  | Description | ||
|  | ----------- | ||
|  | 
 | ||
|  | The LM77 implements one temperature sensor. The temperature | ||
|  | sensor incorporates a band-gap type temperature sensor, | ||
|  | 10-bit ADC, and a digital comparator with user-programmable upper | ||
|  | and lower limit values. | ||
|  | 
 | ||
|  | Limits can be set through the Overtemperature Shutdown register and | ||
|  | Hysteresis register. |
