Output with 8mA drive and 1mA sink capability. AIN - Input pin(Analog) PIN NO PIN NAME TYPE PWR DESCRIPTION 1 VCC PWR 3VCC Power Pin 2 D+ AIN 3VCC Positive connection to remote temperature sensor (ex: thermal diode anode) 3 D- AIN 3VCC Negative connection to remote temperature sensor(ex: thermal diode cathode) 4 SST ILv/OD8-S1 3VCC Intel SST hardware monitor interface. 5 GND PWR 3VCC Ground 6 ALERT# OD12 3VCC Active LOW output. Used as SMBus alert or Interrupt 7 SDA INts/OD12 3VCC Serial bus data 8 SCL INts 3VCC Serial bus clock 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. |
