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.

FEATUREs
✦ Provide 1 on-chip local and 1 remote temperature sensing
✦ ±1 °C accuarcy on remote channel and ±3 °C accuarcy on local channel
   ◾ ±1 °C (+60 °C to +100 °C, remote)
   ◾ ±3 °C (+60 °C to +100 °C, 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
