Abstract: An electronic control unit (ECU), for use with an internal combustion engine, determines whether an abnormal combustion has occurred in the engine. The ECU uses a sensor signal amplifier to amplify a sensor signal from a sensor by changing an amplification power of the sensor signal and an A/D converter to convert the sensor signal amplified to a digital signal (i.e., a digitized sensor signal). The ECU uses an abnormal combustion detector to determine whether an abnormal combustion has occurred based on a characteristic of a waveform of the digitized sensor signal, and performs an abnormal combustion prevention control to prevent the abnormal combustion when an abnormal combustion is detected. An amplification controller is used to set the amplification power of the sensor signal amplifier based on the amplitude of the digitized sensor signal and a determination result of the abnormal combustion by the abnormal combustion detector.

Abstract: A main body of an electronic part has multiple electrodes, to which multiple terminals are respectively connected. The terminals include a normal terminal and a fuse terminal, each of which extends from lands formed in a printed board so as to hold the main body at a position above and separated from a board surface of the printed board. The fuse terminal has multiple leg portions divided by slits. A first leg portion forms an electrical path portion having a cut-off portion, a width of which is smaller than that of other portions of the electrical path portion. A second leg portion has a first supporting leg and a second supporting leg, which are arranged at both sides of the first leg portion. Each of the supporting legs is connected to each of dummy lands formed in the printed board.

Abstract: An electronic control device includes a turn-on restriction section capable of performing a restriction operation to restrict a turn-on speed of a switching element. The turn-on restriction section includes a comparator. The comparator receives a voltage of a main terminal of the switching element connected to a smoothing circuit and determines whether the voltage of the main terminal of the switching element reaches a threshold voltage. The turn-on restriction section performs the restriction operation for a predetermined time from a start of a turn-on period in which the switching element is turned on. The turn-on restriction section stops the restriction operation after the predetermined time has elapsed. The predetermined time is set to a time from the start of the turn-on period until the voltage of the main terminal of the switching element reaches the threshold voltage.

Abstract: A switching power supply device includes a switching circuit and a control circuit. The switching circuit includes multiple switching elements, an inductor, and a capacitor. The control circuit compares an input voltage of the switching circuit with a predetermined threshold voltage set for an operation switch, and controls the switching circuit to perform the operation switch between at least two power control operations based on a comparison result. The at least two power control operations includes at least two of a buck operation, a buck -boost operation, or a boost operation. The control circuit further performs an inrush current restriction operation in response to the operation switch in order to restrict a flowing of an inrush current to one of the switching elements, which turns on and outputs the input voltage through the inductor in response to the operation switch.

Abstract: A load driving device includes a driving switching element, an interrupting part, a short-circuiting switching element, and a protecting element. The driving switching element drives a load by controlling energization to the load. The interrupting part is disposed on an energizing path to the load. The interrupting part is not melted by a driving current to the load and is melted by an interrupting current larger than the driving current so as to interrupt energization to the load. The short-circuiting switching element is connected in parallel with the load and applies the interrupting current to the interrupting part. The protecting element protects the short-circuiting switching element.

Abstract: A power supply device comprises: a first linear regulator, which receives a voltage from a direct-current power supply at all times and outputs a first voltage; a step-down switching regulator, which receives the voltage from the direct-current power supply through a path via a power supply switch and outputs an intermediate voltage, and a second linear regulator, which receives the intermediate voltage and outputs a second voltage. The power supply device outputs a higher one of the first voltage and the second voltage. The first linear regulator has a smaller current consumption and a higher minimum operating voltage than the second linear regulator. When the voltage supplied from the direct-current power supply is lower than or equal to a predetermined threshold value, the switching regulator drives a main switching component interposed in series with a voltage input-output path to turn on at all times. The second linear regulator executes an output operation of the second voltage during a full-on period, during which the main switching component is driven to turn on at all times.

Abstract: A main body of an electronic part has multiple electrodes, to which multiple terminals are respectively connected. The terminals include a fuse terminal and a normal terminal, each of which extends from the main body to a printed board so that the main body is supported at a position above and separated from a board surface of the printed board. The fuse terminal has an intermediate portion between an electrode-connected portion and a land-connected portion. The intermediate portion has a cut-off portion having a smaller width than other portions of the fuse terminal, so that the cut-off portion is melted down when excess current flows in the fuse terminal. The intermediate portion extends in a direction parallel to the board surface or in a direction inclined to the board surface at an angle smaller than 90 degrees.
