Digital Thermometer Temperature Monitor. Max6622 and control
An introduction to the innovative work of the computer. Other functions are included. In the computer. Therefore, increasing the capacity of computers. To meet the needs of a large number of integrated data processing more and more into the host chipset. CPU and chipset work Frequency increases. Frequent chipset and clock speed is more heat. The space heating distribution system is a difficult problem. How to balance system performance. System of comfort. (Read the PC fan speed noise temperature). And how long it takes the subject of computer-aided design, the paper is as follows. The temperature of the MAX6622 and control
2 MAX6622 MAX6622 MAXIM is an accurate description of the multi-channel company. Check the temperature inside. A / D converter in the circuit directly to a digital signal output. The device has a high accuracy. The quick response and small. Low power consumption and simple interface control software. Widely used in desktop notebook server Workstation and check the temperature of other systems. Other.
Precision multi-channel temperature sensor. MAX6622 to the Temperature in the country and to monitor 4-way remote control temperature. All channels are set temperature threshold alarms. Measured channel temperature exceeds threshold. Status the relevant public register bits. Two drains open and clear warning of the state government to set up a somewhat less consistent. Interface serial 2 - wire bus system Management Standard Operating bytes written and read byte for byte order may be also for the temperature data and set alarm threshold to be read. MAX6622 temperature in work. -40 125, 16 - pin SOIC packages.
2.1 feature set. Pin 2.2 and detailed work.
MAX6622 Pin Configuration in Figure A detailed functional pins, see table. 1 below.
2.3 MAX6622 precision temperature modes. 5 channel LCD display and a temperature sensor temperature in channel 4-channel remote sensor, box alarm with programmable threshold temperature for each. Channel 1 and Channel 4 is also programmable threshold temperature through the SMBus serial interface and exporter dedicated to achieving communication alarm. MAX6622 send out warning and clear. Is more than setting the software to be used to the temperature threshold claims to be. Sharing for the interruption alert expression that combines a fan. Switching system or other temperature control. Other circuits.
2.3.1 Mode conversion ADC.
Mode conversion by default. MAX6622 channel first by a measurement, followed by Channel 2, Channel 3, local television channels. 4, began to change. And the change is stored in the appropriate temperature. Registration Information
2.3.2 Low power consumption in standby mode.
The configuration bits. STOP register 1, a place in the software standby mode. STBY low, to buy in the hardware standby mode. Software standby mode is set for ADC and reduces the current consumption of about 30mA to break the hardware clock. ADC Standby Mode and 350mA power supply with software or hardware standby mode. Data stored in memory and interface. SMBus is used to start when a voice SMBus signals are identified. SMBus, Time-out period of activation. SMBus enabled for you to create the power consumption. If you go orders will be converted. - Back, the conversion cycle is interrupted. And registers the temperature does not update the previous data remains unchanged and can
2.3.3 Interrupt mode warning.
Inside or outside when the temperature is reached. Limited the maximum temperature over the noise of the warning. ALERT can proceed. - Open multiple devices to interrupt the normal lines. All of a series of interruptions. Alert 3 to register on the sign.
2.3.4 apparent temperature alarm -
MAX6622 has two remote-alarm threshold is used for registration information up to temperatures above the temperature of the output register to . Delete Measured channel temperature is higher than the corresponding threshold temperature stored in the registry. Create an image signal. To measure the temperature of the Fan to send a warning allow. To start the clock frequency is closed or the destruction of the component should be avoided.
3 circuits computing in general. CPU heat source for the biggest addition, a Graphics Processing Unit. (GPU), memory, DDR, disk, drives, and the optical, to control the temperature and composition. Included in these temperature components in the realization of the remote diode is used. Temperature sensors can directly detect the temperature within the core. CPU and precise temperature control.
MAX6622 application circuit shown in Figure usual. 2 Remote Temperature accuracy depends on factors in the ideal diode from a distance. The temperature of the IC diode according to the rule below. Type PNP DXP_, the EC of the transistor can be connected. DXN_ can connect to the database. When the temperature channel is already on the road. DXP_ DXN_ streets and empty.
DS, DC, the inhibition the AF signals. If electromagnetic interference is a great need for a connection between DXP_ and DXN_ 2200 pF capacitor filter helps but not more than 3 300pF, because the Increase the current flowing through a fault in the changes caused.
4 software, the first set of configuration registers Employment MAX6622 in normal mode subscription criteria alarm limit temperature when measured temperature is higher than the corresponding threshold. Register Channel temperature, clear the enable bit used to enable the fan to send a warning to restart the clock or take the system down to prevent the destruction of components. Position clear. Remain in force until the temperature is below capacity. Limited currently the temperature setting negative values. Hysteresis of 4 at room temperature so it stays at a certain temperature After this work may be subject to the microprocessor. MAX6622 temperature monitor system is a separate function, automatic thermostat. Main-stream of the program in Figure 3
Software design using the C language. Much to improve the efficiency of development and debugging, documenting the same time easy to understand. Produces easy to transplant. integrate environmental with IAR C compiler environment and language C430 Workbench debug C - SPY compiled, downloaded directly to the chip. Flash Memory and offline. User-friendly Interface. Debugging software, which can be seen in the registration of all online content for the benefit of a one-step operation. Online - Real-time observation of the definition of each variable the value. The following is a portion of the code.
5 Conclusion.

Graphics Chipset answers about the fan blowing on the graphics?
I have a special XFX nForce 790i Mobo and chip fan was hot air directly out of my Graphics. Card for my computer when I have problems running the game, so thought this could be the problem I chipset fan, removed the. the case opened and put a high powered fan blows the house. In general, and the CPU. 35 degrees Celsius. I have a heat sink cooled by the fan. Arctic replaced by Intel. I'm still trying to figure out why it is that is does not start from warming. Any help. That's cool. Pretty much new computer that does not). Very difficult to drive (Seagate 7200 250 This default has occurred since the operating system. Installation (32 Vista) I use a program was read to the core temperature. I think since restrting CPU dont I think it's the mobo or memory. But I could be wrong also, it will randomly new any time if I play sometimes on the internet surf.
A little more detail is required. That will happen? From you or not. Restart the computer 'cause that is not displayed when the game . Play Do you have software that monitors the temperature of CPU and GPU, or not? If not, try CPUID. HWMonitor "If your CPU runs at 35 ° C, that's fine too, I certainly not too hot. What do you have installed recently. This one? I would leave that fan on the chipset. ... If the chipset will overheat. Do you want to replace the motherboard. ... You do not know that
