摘要： The present disclosure provides a brushless motor driving circuit capable of clamping an output voltage at a proper voltage, even when a power source voltage changes. Namely, a pre-driver circuit generates a voltage for driving a brushless motor from a source voltage by turning on/off first and second PMOS transistors and first and second NMOS transistors in an H bridge circuit of a drive voltage generating circuit, and applies the voltage to a coil of the brushless motor. A first clamp circuit turns on/off the first NMOS transistor on the ground side so that the output voltage at a first output terminal becomes equal to or lower than the source voltage. A second clamp circuit turns on/off the second NMOS transistor on the ground side so that output voltage at a second output terminal becomes equal to or lower than the source voltage.

摘要： A brushless motor driving apparatus that includes a rotation signal output component, a half-cycle signal generating component, a plurality of counters, and a duty control signal generating component is provided. The plurality of counters, each of which uses a different bit number to count, repeatedly resets a count value and restarts a count operation for every bit number, resets a count value together with rising or falling of a half-cycle signal, and outputs a pulse signal which is inverted for every reset that occurs while the count operation is being performed. The duty control signal generating component generates a duty control signal to determine a duty ratio of a control signal to control driving of a single-phase brushless motor, based on at least two pulse signals selected from the pulse signals output from the plurality of counters.

摘要： A motor speed regulating circuit includes a speed signal generator for generating a speed signal having a frequency proportional to the speed of the motor, synchronously with the rotation of the motor. A time difference detector is used for detecting a time difference between the period of the speed signal and a predetermined standard time. A control voltage generator is used for generating a speed control voltage to be applied to the motor in accordance with a detected time difference and feedback-controlling the speed of the motor in accordance with the standard time. A starter is used for starting the motor after the motor is stopped. The motor can be reliably restarted after it has been stopped.

摘要： A semiconductor integrated circuit device incorporates a voltage step-up (boost) circuit which produces a stepped-up (boosted) voltage higher than the power voltage based on a periodic pulse signal generated internally or supplied from the outside. The stepped-up voltage is supplied to the emitter of a pnp driving transistor that produces a drive current for the output transistor on the voltage source side which is the one of a pair of npn output transistors in push-pull configuration. The voltage step-up circuit has its current supply capacity varied in response to the current flowing through the output transistor or driving transistor.

摘要： An information processing apparatus employs a liquid crystal display and a fluorescent lamp for backlighting the screen of the liquid crystal display. A lighting circuit for supplying alternating current lighting power to the fluorescent lamp receives input power from either a commercial alternating current power source or from a direct current battery. The level of the lighting power supplied to the fluorescent lamp is determined based upon a determination of whether the input power is being supplied from the commercial power source or from the battery.

摘要： A two signal amplifying system is constructed of first and second BTL amplifiers each including a phase splitter and first and second push-pull output circuits. In each of the first and second push-pull output circuits, output transistors are connected between a power source and output terminals, and detectors for detecting the operating states of said transistors are connected with the output transistors constituting the aforementioned first and second push-pull output circuits, respectively. The outputs of those two detectors are fed to a control circuit. The output of the control circuit renders the two output transistors nonconductive in case at least one of the two output transistors deviates from a predetermined operating range.
