摘要： A temperature protection circuit comprises means adapted to compare the temperature being monitored with each of threshold temperatures and judging that the temperature being monitored reaches a threshold temperature when the temperature being monitored is maintained at the threshold temperature or more for a predetermined confirmation period, means adapted to set a longer confirmation period as the threshold temperature compared with the temperature being monitored is lower, means adapted to generate one of corresponding temperature protection signals (Sarm, Slmt, Stsd1, Stsd2) according to the judgment of which threshold temperature the temperature being monitored reaches. With this constitution, temperature protection operation can be preformed with high accuracy and high safety without unnecessarily narrowing the range of the operating temperature of an IC to be protected.

摘要： A switching regulator type power supply apparatus that converts an input voltage and then feeds the voltage thus converted to a smoothing circuit, and that operates in such a way that an output from the smoothing circuit becomes equal to a predetermined output voltage includes a control circuit for generating a control signal by a PWM scheme so that the output becomes equal to the predetermined output voltage, and a switching element that is switched by the control signal so as to convert the input voltage and feed the voltage thus converted to the smoothing circuit. Here, based on an external signal for turning on/off an output of the output voltage, a supply path for supplying an operating power to elements constituting the control circuit is switched between a conducting state and a non-conducting state.

摘要： A battery charger outputs a high voltage even when a power supply device having a rechargeable battery is not connected to the battery charger so that the battery charger can supply the high voltage to the power supply device whenever the power supply device is connected to the output terminal of the battery charger. This battery charger has periodic signal producing means for supplying a periodically varying periodic signal to the output terminal by charging and discharging a capacitor connected to the output terminal, and detecting means for checking whether the power supply device is connected to the battery charger or not by checking through a filter whether the periodic signal is present at the output terminal or not. Thus, although the battery charger has no mechanical switch, it can detect the presence of the power supply device.
