The Hall sensor generates a voltage or a current signal proportional to the strength of the current to be sensed.Type: ApplicationFiled: August 14, 2013Publication date: November 6, 2014Applicant: FEELING TECHNOLOGY CORP.Inventors: TENG-TSAI LIN, WEN-JUNG SU, HSUAN-CHUAN CHEN -
Patent number: 8243474Abstract: The control circuit for power supplying includes a driving module and a control module, wherein the driving module includes a first switch, a second switch, a third switch, and a fourth switch. In a first power supply mode, the first switch and the second switch are turned on, and the third switch and the fourth switch are turned off. The load current flows to the ground terminal via the first switch, the inductive load, and the second switch. When the control module sends a switching signal to the driving module, the first switch and the second switch are turned off and the third switch and the fourth switch are turned on, and the load current flows to the high potential terminal via the fourth switch, the inductive load, and the third switch due to the current inertia.Type: GrantFiled: October 22, 2009Date of Patent: August 14, 2012Assignee: Feeling Technology Corp.Inventors: Hsuan-Chuan Chen, Teng-Tsai Lin

Patent number: 8106611Abstract: A switching regulation circuit for a dual-winding motor apparatus is provided. The switching regulation circuit comprises a gate-controlled device and a driving circuit. When one of the two windings generates an induced voltage signal greater than a threshold value, the driving circuit generates an output signal for turning on the gate-controlled transistor. Thereby, a parasitic diode of the gate-controlled device will not be turned on and damage the entire circuit.Type: GrantFiled: August 4, 2008Date of Patent: January 31, 2012Assignee: Feeling Technology Corp.Inventors: Hsuan-Chuan Chen, Teng-Tsai Lin

Patent number: 7412156Abstract: The present invention discloses a brushless dc motor driver circuit capable of reducing vibration or shock noise and a method thereof. The brushless dc motor driver circuit of the present invention comprises a Time-Voltage Digital/Analog Converter. The Time-Voltage Digital/Analog Converter further comprises: at least one magnetic field detecting circuit, at least one counter, and a signal processor. The Time-Voltage Digital/Analog Converter is connected to a driver circuit of a brushless dc motor and detects the periodically varying magnetic field of the brushless dc motor. Based on the rising time and the falling time of the preceding magnetic field variation, the Time-Voltage Digital/Analog Converter calculates the elapsed time from the current phase-change point and generates a linearly rising signal and a linearly falling signal. Then, those two sets of analog signals are used to drive the brushless dc motor. Thereby, the vibration or shock noise of the brushless dc motor is reduced.Type: GrantFiled: November 8, 2006Date of Patent: August 12, 2008Assignee: Feeling Technology Corp.Inventors: Teng-Tsai Lin, Hsuan-Chuan Chen, Wen-Jung Su

Patent number: 6788017Abstract: A period adjustment circuit of disconnection and restart IC comprises a second capacitor, which is connected to a resistor and a transistor connected in parallel. One end of the resistor is connected between the disconnection and restart IC and the first capacitor. When lockup of a fan motor occurs, in addition that an IC current source charges the first capacitor, the second capacitor also charges the first capacitor via the resistor until the voltage of the first capacitor reaches a disconnection voltage. The IC then enters into the disconnection state, and the voltages of the two capacitors are equal so that the second capacitor no longer charges the first capacitor. Next, the IC current source simultaneously charges the first and second capacitors until the voltage of the first capacitor reaches a system reset voltage. The first capacitor is then discharged to a restart voltage by the IC.Type: GrantFiled: September 20, 2002Date of Patent: September 7, 2004Assignee: Feeling Technology Corp.Inventors: Teng-Tsai Lin, Ping-Yen Chen

Patent number: 5682348Abstract: The object of present invention is to provide a programming switch for non-volatile memory wherein output voltage Vout versus input voltage Vin satisfies the following relations: (1) While Vin is logic "0", Vout is logic "0"; (2) While Vin is logic "1", Vout is about the value of programming voltage Vpp if programming is executed and about the value of supply voltage Vcc if programming is not executed. The present invention is characterized in that it can be utilized in general non-volatile memory and the supply voltage needed can be as low as 2 volts, resulting in body effect almost giving no influence.Type: GrantFiled: April 9, 1996Date of Patent: October 28, 1997Assignee: Myson Technology, Inc.Inventors: Yi-Pin Lin, Teng Tsai Lin
