Fintek F75375S (sensor)

Added by ALMICO on 24 sep 2005

F75375S is a system hardware monitoring and automatic fan speed controlling IC specific designed for graphic cards and mini PC etc. The F75375S can monitor several critical hardware parameters of the system, including voltages, temperatures and fan speeds which are very important for the system to work stably and properly. An 8-bit analog-to-digital converter (ADC) was built inside F75375S. The chip can monitor up to 4 analog voltage inputs, 2 fan tachometer inputs and 2 remote temperature sensors. The remote temperature sensor is suggested to be performed by thermistor, transistor 2N3906 and CPU thermal diode. The F75375S can provide automatic fan speed control so that the system can operate at the minimum acoustic noise. This chip support not only PWM duty mode but also linear mode for fan speed control. Internal oscillator was built in this chip and user can use external clock input if users need accurate fan speed count. Also 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 software MyGuard or other management application software. The F75375S is in the package of 150mil 16-pin SOP and powered by 3.3V.
