    摘要: A motor drive device includes a charging detection and reverse current prevention portion and a pulse selection control portion. The charging detection and reverse current prevention portion detects a charging state of a secondary battery that is charged by an electromotive force of a solar battery, the charging state indicating whether the secondary battery is being charged. The pulse selection control portion causes a first drive pulse for driving a motor to be generated and, in a case where the charging state that is detected by the charging detection and reverse current prevention portion is different after the first drive pulse has been output from what it was before the first drive pulse was output, causes a second drive pulse for driving the motor to be generated.

    摘要: A detection interval in which the rotation status of a stepping motor is divided into a first interval immediately after driving executed by a main driving pulse, a second interval later than the first interval, and a third interval later than the second interval. The driving is executed by a correction driving pulse and the main driving pulse is increased, when a control circuit drives the stepping motor in a driving way different from a driving way at the time of exceeding a predetermined voltage in a case where the voltage of a secondary battery is lowered to be equal to or less than the predetermined voltage and when a rotation detection circuit and a detection time comparison determination circuit detect an induced signal exceeding a first reference threshold voltage in the first interval and the second interval and do not detect the induced signal exceeding a second reference threshold voltage lower than the first reference threshold voltage in the third interval.

    摘要: It is configured to include: a secondary battery as a power supply that supplies power at least to a stepping motor; a rotation detection portion that detects a rotation state of the stepping motor; a control portion that drives the stepping motor by selecting a drive pulse having energy corresponding to the rotation state of the stepping motor from a plurality of drive pulses; and a solar battery that charges the secondary battery. Upon determination that it is possible to rotate the stepping motor by an overcharge indicating drive pulse having predetermined energy, the control portion drives the stepping motor by changing a current drive pulse to an overconsuming drive pulse having larger energy than the overcharge indicating drive pulse. It thus becomes possible to suppress deterioration of a secondary battery caused by overcharge without having to provide a dedicated voltage detection circuit, such as a comparator circuit.

    摘要: A secondary cell supplies drive power to a motor of an analogue electronic timepiece, and a state detection circuit detects whether or not a state at the time of driving the motor is a predetermined state. A cell voltage detection circuit detects a voltage of the secondary cell at intervals corresponding to a detection result by the state detection circuit. A control unit drives the motor by selecting a drive pulse of energy corresponding to a detection result of the cell voltage detection circuit out of drive pulses of different energies. When the state detection circuit detects that a state at the time of driving the motor is the predetermined state, the cell voltage detection circuit detects the voltage of the secondary cell at intervals shorter than intervals when the state detection circuit detects that the state at the time of driving the motors is not the predetermined state.

    摘要: A voltage detection circuit detects a voltage of a secondary cell that powers a stepping motor. A rotation detection circuit detects a rotation state of the stepping motor, and a control unit selects a main driving pulse for driving the stepping motor based on the detected rotation state from plural kinds of driving pulses having different energies. An analog display unit announces that the voltage of the secondary cell becomes a predetermined reference voltage when the voltage detection circuit detects that the voltage of the secondary cell becomes the predetermined reference voltage. When the control unit selects a predetermined main driving pulse before the voltage detection circuit detects that the voltage of the secondary cell becomes a current reference voltage, the control unit sets the reference voltage to the predetermined reference voltage higher than the current reference voltage.
