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： In an electric load driving device, in the case of a high-side output mode, an output FET is supplied, when connected with a higher-potential side than a load, at its gate with a boosted voltage higher than a battery voltage in response to one control signal as selected from two control signals by a switch signal. In the case of a low-side output mode, the FET is supplied, when connected with a lower-potential side than the load, at its gate with the battery voltage in response to the selected signal. These cases are switched in response to a signal indicating the bit value of the output mode setting data which are stored in advance in a nonvolatile memory.

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： An ECU has a main IC and at least one auxiliary IC, with at least the auxiliary IC driving one or more MOS FETs to control supplying of power to respective electrical loads, e.g., in a vehicle. A stepped-up voltage, higher than the circuit power source voltage, is generated within the main IC and supplied to each auxiliary IC, for driving gate electrodes of the MOS FETs. Electrical noise produced by operation of a voltage step-up circuit in the main IC is effectively suppressed by elements that are coupled only to a power source terminal of the main IC alone.

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.
摘要翻译：电源PS包括用于检测从外部电压源输入的电压电平Vs的电压检测电路VD，与BS并联连接的引导带电路BS，以及与BS输出端子连接的平滑电路SM，以及调节IC 与BS和FET连接。调节IC包括VD，晶体管Tr和电容器C.当PS开关导通并且当VD检测到Vs（其曾经下降）达到上升基准时，VD产生的高电平驱动信号变为低电平信号，从而关断与C连接的Tr。因此，直到Tr完成充电C为止，依赖于SM输出的脉冲宽度调制（PWM）信号的占空比逐渐变大，从而确保通过转动来防止冲击电流通过PWM信号对FET进行通/断。

摘要： A direct current motor for an engine throttle control is driven with a motor current of 100% duty ratio, when a throttle valve is to be moved from one throttle position to another or when the movement of the throttle valve is to be braked. The motor current is limited to a limit level, when the motor locks, that is, when the motor current continues to be in excess of the limit level for more than a predetermined period. The motor may be driven with a limited current at initial stages of moving the throttle valve, and with a further limited current when the motor lock is detected. The motor current is finally shut off, when the throttle valve is not rotated to the target position after the continuation of the limitation of the motor current for more than a predetermined period.
