F75393

1. General Description

The F75393 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 F75393. The

F75393 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 transistor or transistor 2N3906. The F75393 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.

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 F75393 provides SMBus address selection. This chip can be used more than 2 pcs

on the same board by different SMBus address enter. The F75393 is in the green package of 8-pin

MSOP/SOP and powered by 3.3V.
