摘要： A resistor testing circuit for a battery charger that tests divisional resistors used to estimate the resistance of a thermistor in a battery pack. The battery charger when activated conducts a self test. In the self test, switches are sequentially switched to form groups of resistors and test the connection state of the resistors groups. When a defect is detected by the self test, the battery charger stops performing charging. When no defects are detected by the self test, the thermistor of the battery pack is used to estimate temperature. The charging current is determined in correspondence with the temperature. Then, charging is started.

摘要： A method and circuit for accurately detecting an output short circuit in a switching regulator. A first transistor and a second transistor are connected in series and driven in a complementary manner. A comparator compares output current, which is generated when the first and second transistors are driven, with a short circuit detection threshold to generate a first short circuit detection signal. A timing controller retrieves the first short circuit detection signal generated by the comparator at a predetermined time to generate a second short circuit detection signal.

摘要： A PWM controller for adjusting an output voltage of a buck and boost converter includes a first saw wave generator, which generates a first saw wave in accordance with the level of the output voltage. A first comparator coupled to the first saw wave generator compares the first saw wave with a first reference voltage and generates a first pulse. A peak hold circuit coupled to the first saw wave generator holds a peak value of the first saw wave. A second saw wave generator coupled to the peak hold circuit generates a second saw wave having a lower limit value that is the peak value of the first saw wave. A second comparator coupled to the second saw wave generator compares the second saw wave with the first reference voltage and generates a second pulse.

摘要： A battery charging circuit and a battery charger that stabilizes operation when switching between charging modes. The battery charging circuit includes first and second transistors that form a current mirror circuit with an output transistor. The source terminal of the first transistor is connected to a first resistor, and the source terminal of the second transistor is connected to a second resistor. Each source terminal is connected to a switch circuit, which controls switching between a trickle charge mode and a fast charge mode. The supply of current to the first and second resistors from the discrete transistors reduces the difference in phase lag resulting from the CR time constant and stabilizes operation in the trickle charge and the fast charge modes.

摘要： A steam iron includes a sensor for detecting and measuring movement of the steam iron. The sensor is coupled to an actuator that regulates the flow of steam via a valve located between a steam chamber and steam outlets. The sensor can detect movement in three directions (X, Y, Z) and adjust steam generation based on speed of movement of the iron and tilt angle. A pre-heater is used to pre-heat water in a water chamber. The pre-heated water is provided to a steam chamber where it is later converted to steam.

摘要： A battery charging circuit that stabilizes operation when switching between charge modes includes first and second transistors. The first transistor has a source connected to a first switch circuit. The first switch circuit connects the second transistor to either one of first and second external terminals. A mode switch circuit generates a switch signal for switching from a trickle charge mode to a fast charge mode. The mode switching circuit provides the switching signal to a comparison circuit. After a predetermined time elapses, the mode switching circuit provides the switching signal to the switch circuit. The comparison circuit lowers a current restriction reference voltage, which determines a charging current value, and returns the current restriction reference voltage to its original value after switching modes.
