6. Functional Description

6.1

General Description

The F75395 is a simple temperature sensor with warning signal output. It includes a local and a remote temperature sensor. Both

measured temperature are compared with its high, low and THERM limits which are stored in the registers. When one or more

out-of-limit events occur, the flags in Status Register will be set and that may cause ALERT output to low. Also, measured

temperature exceeding THERM limit may cause THERM output to low.

6.2

The warning message

Pin4 and pin6 act as warning message when the temperature exceeds it threshold point.
