Among them, the _ connection method and 2 lines in the table are burned out, resulting in no FG signal output. In view of this, this creation aims at the above-mentioned problem, and proposes a fan control circuit device with a protective effect to effectively solve the problems of the conventional technology. [New content] "The main purpose of this creation is to provide a kind of wind-silk weaving device with protection. With the setting of reverse two return, the operator will not burn the circuit when the connection is wrong. The other purpose of the creation is to provide a kind of fan control circuit device with protection function, so that the electronic equipment using the fan will not cause damage to the device due to the wrong connection of the fan. * According to this creation-a fan control with protection The circuit set includes-the fan input power is provided by the power input terminal, and the fan circuit also includes a _ sampling element to detect the fan motor and connected to the transmission terminal-the FG signal, and then subtract the FG signal calculation The speed of the fan motor, in which a _reverse diode is provided between the signal transmission end and the sampling element, to prevent damage to this protection circuit due to misconnection. Under the specific implementation of Nahe_guan scale plus outline, t more It is suspected to explain the purpose, technical content, characteristics and achieved effect of this creation. 6 M280597 [Implementation Mode] This creation system is a kind of fan control circuit with protective function, please refer to the figure- This wind-miscellaneous circuit 1 is copper to detect the corresponding speed of the fan motor under different operating conditions. The fan control circuit 1 includes a power input terminal 12 to provide power to the fan motor 10, and the power input terminal 12 A -bias resistor 14 is provided to make the electric power required by the fan 10 smoothly, and the fan control circuit 1 further includes a -sampling element 16 for measuring the operation of the fan motor 10 and the frequency of the operation is- Generate (Frequency Frequency Generation, FG) signal to transmit, this sampling element • 16 type is a sampling transistor 'and this sampling element 16 is connected to a-signal transmission terminal 18, this signal transmission terminal 18 can transmit the FG signal, Among them, a reverse diode 20 is provided between the signal transmitting end 18 and the sampling element 16, so as to prevent the fan control circuit from being damaged due to the operator's incorrect connection.
