1 Kernel driver lm95245 2 ================== 3 4 Supported chips: 5 * National Semiconductor LM95245 6 Addresses scanned: I2C 0x18, 0x19, 0x29, 0x4c, 0x4d 7 Datasheet: Publicly available at the National Semiconductor website 8 http://www.national.com/mpf/LM/LM95245.html 9 10 11 Author: Alexander Stein <email@example.com> 12 13 Description 14 ----------- 15 16 The LM95245 is an 11-bit digital temperature sensor with a 2-wire System 17 Management Bus (SMBus) interface and TruTherm technology that can monitor 18 the temperature of a remote diode as well as its own temperature. 19 The LM95245 can be used to very accurately monitor the temperature of 20 external devices such as microprocessors. 21 22 All temperature values are given in millidegrees Celsius. Local temperature 23 is given within a range of -127 to +127.875 degrees. Remote temperatures are 24 given within a range of -127 to +255 degrees. Resolution depends on 25 temperature input and range. 26 27 Each sensor has its own critical limit, but the hysteresis is common to all 28 two channels. 29 30 The lm95245 driver can change its update interval to a fixed set of values. 31 It will round up to the next selectable interval. See the datasheet for exact 32 values. Reading sensor values more often will do no harm, but will return 33 'old' values.
