| 摘要 |
The present invention is a brushless DC fan motor driving circuit, comprising a control unit, a Hall element, a temperature sensor with negative temperature coefficient, and a motor, as tied in with a plurality of resistors, capacitors, diodes and transistors. Accordingly, through sensing environment temperature by the temperature sensor and feeding back the temperature sensed to the motor to control the resolving speed, the ambient temperature of the system is maintained.
