F75383/F75384

1. General Description

The F75383/F75384 is a temperature sensor IC with alert signal which is specific designed for notebook,

graphic cards etc. An 11-bit analog-to-digital converter (ADC) was built inside F75383/F75384. The

F75383/F75384 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.

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 F75383/F75384 is in the package of 8-pin MSOP/SOP and powered by 3.3V.

2. Features

Provide 1 on-chip local and 1 remote temperature sensing

±1 ^oC (+60 ^oC to +100 ^oC, remote)

±3 ^oC (+60 ^oC to +100 ^oC, local)

ALERT# output for SMBus alert

THERM# output for over temperature alert or for system shut down

Programmable THERM# limits and THERM# hysteresis

Programmable alert queue

Programmable limited and setting points(alert threshold) for all monitored items

2 wire SMBus interface

3VCC operation and in 8-SOP/8-MSOP green class package

8-MSOP Package – F75383M/F75384M ; 8-SOP Package – F75383S/F75384S

The difference between F75383 and F75384 is SMBus address ID and they have the following

SMBus slave address:

F75383
