1. General Description
2. Features
3. Key Specifications
The F75367 is a temperature sensor IC with ß compensation and supports I2C to SST Master Bridge
function. This chip provides 2-remote temperature sensor, 1-local temperature sensor and 6-remote
temperature input by SST Master. The local temperature sensor can be applied to sense environment
temperature without any component. The 2 remote temperature sensors can be performed by CPU
thermal diode or transistor 2N3906. The F75367 also can support new generational 45nm CPU
temperature sensing by varied ß of CPU. Besides 3 sets temperature sensors, the F75367 also can read
6 temperature inputs from other devices by SST interfaces. The host can read the extra 6 sets
temperature by I2C interface (I2C to SST Master Bridge). Totally the F75367 can support 9 temperature
outputs for host fan control by I2C.
The F75367 is in the green package of 8-pin SOP and powered by 3.3V.
Provide 1 on-chip local and 2 remote temperature sensors
Support 6 temperature inputs from external sensor devices (ex: F75395)
Beta-compensation support for new generational CPU.
