Micro Cooling Fan auto-recovery function

"Micro Cooling Fan" auto-recovery function requires the feature to start the fan rotor locked into small fan current moment (myopia zero A) lock, release the rotor, the rotor is stopped, a few seconds (stop state After the length of time by the IC itself conventional design or special needs for design changes) automatically released by the IC internal voltage of the fan guide can resume work, "Micro Cooling Fan" starting from the resting state the rotor starts operating normally. The main function is to prevent the installation process reasons the fan rotor by external factors cause the rotor to be stuck or dead fan, often time is affected by a large current caused by the fan burned. Of course, the fan itself high quality shock will be small, but the first two were, but it is difficult to overcome. To solve this problem, we can try to use larger size fan. Should be under the same amount of wind, the big "Micro Cooling Fan" operating noise at low speed to less than a small fan operating noise at high speed. Another factor is that we tend to ignore the fan bearings.
