Patent number: 8729839Abstract: A BEMF detection circuit generates a rotation detection signal indicating a comparison result between electromotive force voltages VU through VW which occur at a terminal of respective multiple coils and an intermediate-point voltage VCOM. A rotor position detection circuit generates a rotor position detection signal indicating a stopped rotor position An internal start-up synchronization signal generating unit generates a predetermined-frequency forced synchronization signal. Upon receiving a fan motor start-up instruction, a driving signal synthesizing circuit generates a driving control signal based upon the rotor position detection signal. Thus, (1) when back electromotive force voltage occurs, a sensorless driving operation is started based upon the rotation detection signal; (2) when it does not occur, the driving control signal is generated based upon the forced synchronization signal. Subsequently, when it occurs, the sensorless driving operation is started based upon the rotation detection signal.Type: GrantFiled: October 25, 2011Date of Patent: May 20, 2014Assignee: Rohm Co., Ltd.Inventors: Toshiya Suzuki, Shinsuke Sano, Atsushi Sato, Eri Kishimoto

Publication number: 20120268047Abstract: The objective of the present invention is to miniaturize a driving circuit of a fan motor. The present invention provides a driving device for driving a fan motor as a three-phase brushless DC motor. An inbuilt Hall component is disposed adjacent to the fan motor and generates a pair of Hall signals corresponding to a rotor position of the fan motor. An internal power source supplies a bias signal to the inbuilt Hall component. A Hall signal processing portion cancels a shift of the pair of Hall signals and amplifies the Hall signal. A driving processing circuit drives the fan motor according to an output signal of the Hall signal processing portion. The driving device is integrated on a semiconductor substrate.Type: ApplicationFiled: March 29, 2012Publication date: October 25, 2012Applicant: ROHM CO., LTD.Inventors: TOSHIYA SUZUKI, NOBUO KOMURA, SHINSUKE SANO
