The F75395 is a temperature sensor IC with ß compensation and alert signal which is specific designed for notebook, graphic cards etc. An 11-bit analog-to-digital converter (ADC) was built inside F75395. The F75395 can monitor two set of temperature which is very important for the system to work stably and properly. This chip provides 1 remote temperature sensor and 1 local temperature sensor. The remote temperature sensorcan be performed by CPU thermal diode or transistor 2N3906. The F75395 also can support new generational 45nm CPU temperature sensing by varied ß of CPU. The users can set up the upper and lower limits (alarm thresholds) of all monitored parameters and this chipcan also issuewarning messages for system protection when there is something wrong with monitored items.
Through the BIOS or application software, the users can read all the monitored parameters of system all the time. And a pop-up warning can be also activated when the monitored item was out of the proper/pre-setting range. The application software could be Fintek's application utility, or other management application software. The F75395 is in the green package of 8-pin MSOP and powered by 3.3V.
