The F75397/394 are the temperature sensor ICs which can support alert signal which is specific designed for notebook, and graphic cards etc. An 11-bit analog-to-digital converter was built inside the IC. The F75397/394 can monitor three sets of temperature which is very important for the system to work stably and properly. F75397/394 provides 1 local temperature sensor and 1 remote temperature sensors. The remote temperature sensorcan be performed by CPU thermal transistor or transistor 2N3906.

The F75397 & F75394 support 2 wire system management bus interface. 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 F75397/394 are in the green package of 8-pin MSOP and powered by 3.3V.
