摘要： When a highly accurate clock is received by a GPS radio wave from a GPS antenna, the highly accurate clock is always generated by locking a phase locked loop (PLL) circuit within a hold-over section of a clock control section in a power supply control unit. When the GPS radio wave cannot be received normally, the highly accurate clock depending on the GPS radio wave is set to a self-running condition not depending on a self-oscillation clock from an internal clock generating section and a time management section automatically corrects the present time data obtained when the standard radio wave is received from a radio wave antenna based on the highly accurate clock. A primary voltage generating section continuously generates the highly accurate clock even when an ignition switch is turned OFF by avoiding voltage variation in battery voltages while the ignition switch is turned ON. Accordingly, the power supply control device can sustain highly accurate time correction and a clock function under any environmental condition and can also control and execution of various functions based on accurate time management.
摘要翻译：当通过来自GPS天线的GPS无线电波接收到高度准确的时钟时，总是通过将锁相环（PLL）电路锁定在电源控制中的时钟控制部分的保持部分内来产生高度准确的时钟单元。当GPS无线电波无法正常接收时，根据GPS无线电波的高度准确的时钟被设置为不依赖于来自内部时钟产生部分的自激振荡时钟的自运行状态，并且时间管理部分自动校正基于高精度时钟从无线电波天线接收标准无线电波时获得的当前时间数据。即使当点火开关接通时，通过避免电池电压的电压变化，当点火开关断开时，一次电压产生部也连续地产生高精度的时钟。因此，电源控制装置可以在任何环境条件下维持高精度的时间校正和时钟功能，并且还可以基于准确的时间管理来控制和执行各种功能。

摘要： There is a need for improving switching regulator characteristics and providing a stable power supply controller. The power supply controller uses a battery and either or both functions of stepping up and stepping down a battery voltage. The power supply controller includes a means that prevents a ripple voltage from occurring by stopping the up conversion function for a switching operation in connection with a battery during a predetermined period without changing conditions for a conventional switching device or smoothing circuit and fast stabilizes a primary voltage using only the down conversion function.

摘要： A load driving and diagnosis system controls the feed and block of a load current flowing into an inductor such as a solenoid. The load driving and diagnosis system holds a counter-electromotive force, which is developed when the load current is blocked, at a voltage higher than a supply voltage so that the load current will decay for a short time. When an overcurrent condition is established in the load driving and diagnosis system because of a short circuit to a power supply, a malfunction of a circuit or destruction thereof may take place. In addition to a voltage holding means that holds a switching circuit output voltage at a predetermined voltage, a voltage holding means having a different predetermined voltage set therein is included. Moreover, a selection switch that switches the predetermined voltages according to a detected overcurrent condition is included.
