The F75303 is the temperature sensor IC which can support ß compensation related application and alert signal which is specific designed for notebook, and graphic cards etc. An 11-bit analog-to-digital converter (ADC) was built inside the IC. The F75303 can monitor three sets of temperature which is very important for the system to work stably and properly. F75303 provides 1 local temperature sensor and 2 remote temperature sensors. The remote temperature sensorcan be performed by CPU thermal transistor or transistor 2N3906. The F75303 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 F75303 is in the green package of 10-pin MSOP and powered by 3.3V.
