摘要： In an ECU, a level adjusting unit communicable to first and second control circuits and a bus transceiver installed in the ECU receives first data and second data respectively transmitted from the first and second control circuits. The bus transceiver is communicable to a communication bus. When the first data and the second data are simultaneously received, the level adjusting unit merges the first data and the second data such that a first electric level of the first data wins with a second electric level of the second data. The level adjusting unit outputs the merged data to the bus transceiver.

摘要： A power supply apparatus that supplies an operating voltage to a microcomputer reliably resets the microcomputer before operation becomes unstable when an external power supply voltage decreases due to interruption. A switching regulator and series regulators are included. An externally supplied power supply voltage is stepped down to generate an intermediate voltage. The intermediate voltage is stepped down to generate an operating voltage for a microcomputer core. The intermediate voltage is stepped down to generate an operating voltage for an I/O port. When the intermediate voltage becomes lower than a reset determining voltage, the power supply apparatus outputs a reset signal to the microcomputer. When the power supply voltage decreases, the microcomputer can be reliably reset and the core can be prevented from operating erratically before the voltage becomes lower than a minimum core operating voltage.

摘要： A switching power supply has first and second switching units and a control unit. Each switching unit has a switching element performing a switching operation to intermittently receive electric current from a battery while accumulating electric power in a coil and discharging this power to an output terminal. A resistor earthed is serially connected with each switching element. The resistance of the first resistor receiving the first current from the first switching element is lower than that of the second resistor receiving the second current from the second switching element. A maximum value of the first current is higher than that of the second current due to the difference between the resistors. The control unit controls the switching operations of the elements to boost the voltage of the battery and stops the switching operations in response to the first current exceeding an upper value.

摘要： A multi-output electric power source device has at least two channels for producing a constant voltage and a constant voltage from a single input voltage. Each channel is provided with a switching regulator in the input stages thereof and a series regulator in the next stage thereof. An over-heat detector circuit is provided in common for both channels. When the over-heating of either one of switching transistors in the channels is detected, the switching regulators turn off both switching transistors thereby to interrupt both output voltages from being supplied to an external circuit. When an over-voltage is detected, series regulators also interrupt the output voltages from being supplied to the external unit.

摘要： The power supply PS includes a voltage detecting circuit VD for detecting a voltage level Vs inputted from an external voltage source, a boot strap circuit BS, andET connected in parallel with BS, a smoothing circuit SM connected with the BS output terminal and a regulating IC connected with BS and FET. The regulating IC includes VD, a transistor Tr and condenser C. Both when a PS switch is turned on and when VD detects that Vs (which once descended) reaches an ascending reference, a high level driving signal generated by VD is changed into a low level signal, thereby turning off Tr connected with C. Thus, until Tr completes charging up C, a duty ratio of a pulse width modulation (PWM) signal dependent on the SM output is made gradually greater, thereby surely preventing a rush current by turning on and off the FET by the PWM signal.
