General Description
cards etc. An 11-bit analog-to-digital converter (ADC) was built inside F75385. The F75385 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 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 F75385 is in the package of 8-pin MSOP and powered by 3.3V.
Features
The F75385 is a temperature sensor IC with alert signal which is specific designed for notebook, graphic
Through the BIOS or application software, the users can read all the monitored parameters of system all
