摘要： A detection circuit is mounted on an electronic device having a communication function, including at least a battery, a CPU, and a communication unit, and is configured to detect the remaining battery charge. An A/D converter performs sampling of a magnitude of a current IBAT discharged from the battery, and converts the current IBAT thus sampled into a digital current value. An interface circuit receives, from the CPU, control data which indicates a period in which there is an increase in the current discharged from the battery. Based upon the control data, a control unit raises the sampling frequency of the A/D converter in the period in which there is an increase in the current IBAT.

摘要： A control circuit is provided for a separately excited DC/DC converter which directly monitors output voltage to detect a short-circuit state, and performs overcurrent protection. A switching controller of the control circuit controls a switching operation of a switching transistor of the separately excited DC/DC converter. A voltage comparator compares the output voltage and a threshold voltage, to detect the short-circuit state. After a predetermined start-up time has elapsed after beginning start-up of the separately excited DC/DC converter, when the voltage comparator detects the short-circuit state, the switching controller halts the switching operation of the switching transistor, and makes detection of the short-circuit state by the voltage comparator non-operative before elapse of the start-up time. After detecting the short-circuit state and halting the switching operation of the switching transistor for a predetermined halt time, the switching controller begins start-up of the separately excited DC/DC converter once again.

摘要： A driving apparatus drives a mover arranged for feedback of a touch panel. A reference voltage generation unit generates a reference voltage having a signal waveform to be applied to the mover. A pulse modulator generates a PWM signal of which duty ratio is controlled by feedback so that a feedback voltage corresponding to a drive voltage to be applied to the mover approaches the reference voltage. A switching element of the DC/DC converter is turned ON/OFF by a PWM signal from the pulse modulator, so that an output voltage of the DC/DC converter is controlled, and a drive voltage corresponding to the output voltage is applied to the mover.

摘要： An output voltage monitoring circuit monitors an output voltage of a capacitor charging circuit. A first sample-and-hold circuit samples and holds a voltage of a connection point of a primary coil of a transformer and a switching transistor. A first monitoring comparator compares output of the first sample-and-hold circuit with a predetermined first reference voltage. When the output of the first sample-and-hold circuit exceeds the first reference voltage, a signal processor executes predetermined signal processing. The first sample-and-hold circuit starts a sampling period after a predetermined first time has elapsed after the switching transistor is turned OFF. When a voltage drop across a detection resistor reaches a third reference voltage, the first sample-and-hold circuit ends the sampling period.

摘要： A control circuit of a DC/DC converter is provided for supplying a driving voltage to a light emitting element. A hysteresis comparator compares a detection voltage that corresponds to the output voltage of the DC/DC converter with two threshold voltages. If the detection voltage is smaller than the lower threshold voltage, the hysteresis comparator outputs a comparison signal at the low level. Otherwise, the comparison signal is set to the high level. The switching control unit uses the comparison signal as a reference. The switching control unit instructs the switching transistor of the DC/DC converter to perform the switching operation during a period when the comparison signal is at the low level. Otherwise, the switching operation is suspended. The control circuit inhibits light emission of the light emitting element during a period when the comparison signal is at the low level. Otherwise, the control circuit permits the light emission.
