F75395
General Description
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
sensor can 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 chip can also issue warning messages for system
protection when there is something wrong with monitored items.
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.
Features
The F75395 is a temperature sensor IC with ß compensation and alert signal which is specific designed
Through the BIOS or application software, the users can read all the monitored parameters of system all
