Limits can be set through the -Overtemperature Shutdown register and Hysteresis register. Each value can be -set and read to half-degree accuracy. -An alarm is issued (usually to a connected LM78) when the temperature -gets higher then the Overtemperature Shutdown value; it stays on until -the temperature falls below the Hysteresis value. -All temperatures are in degrees Celsius, and are guaranteed within a -range of -55 to +125 degrees. - -The driver caches the values for a period varying between 1 second for the -slowest chips and 125 ms for the fastest chips; reading it more often -will do no harm, but will return 'old' values. - -The original LM75 was typically used in combination with LM78-like chips -on PC motherboards, to measure the temperature of the processor(s). Clones -are now used in various embedded designs. - -The LM75 is essentially an industry standard; there may be other -LM75 clones not listed here, with or without various enhancements, -that are supported. The clones are not detected by the driver, unless -they reproduce the exact register tricks of the original LM75, and must -therefore be instantiated explicitly. Higher resolution up to 16-bit -is supported by this driver, other specific enhancements are not. - -The LM77 is not supported, contrary to what we pretended for a long time. -Both chips are simply not compatible, value encoding differs. |
