摘要： The present invention is to provide a power supply control apparatus which can connect a ground to a suitable electric potential when the ground is disconnected. The power supply control apparatus includes a control circuit having a switch element and a switch control unit, and a load. One terminal of load is connected to a direct-current power supply through the switch element, and the other terminal is connected to a ground electric potential. The switch control unit has a ground terminal connected to the ground electric potential and outputting a ground current flowing toward the ground electric potential. The control circuit includes a bypass device having a load side bypass system for passing the ground current to the ground electric potential through the load when connection between the ground terminal and the ground electric potential is disconnected. The load includes impedance for changing the electric potential of ground terminal into an electric potential in which the switch control unit stably acts when the ground current flows.

摘要： Provided are an overcurrent protection device and an overcurrent protection system which can provide time differences among the timings for executing the retry operations among a plurality of overcurrent protection devices connected to a common power supply. When a battery voltage (VBA) becomes a value equal to or lower than a threshold voltage after an FET (Q1) of an IC circuit (51-1) is turned on, all FETs (Q1) of the respective IC circuits are turned off, and a time until the battery voltage (VBA) reduces to a value lower than a threshold voltage after the turning-on of the FET (Q1) is clocked. When the time is smaller than 400 μsec, the count value N is incremented. Further, turning-on of the FETs (Q1) is repeated after the lapse of the standby time (Tp) set randomly. When the count value N reaches 7, the FET (Q1) of the IC circuit 51-1 is held in the turned-off state. Accordingly, only the load-driving circuit at which the dead short occurs can be stopped and the driving of the other load-driving circuits can be continued.
摘要翻译：提供一种过电流保护装置和过电流保护系统，其可以在连接到公共电源的多个过电流保护装置之间提供用于执行重试操作的定时之间的时间差。当IC电路（51-1）的FET（Q1）导通后，当电池电压（VBA）变为等于或低于阈值电压的值时，各IC电路的所有FET（Q1）都被断开，并且在FET（Q1）导通之后，直到电池电压（VBA）降低到低于阈值电压的值为止的时间。当时间小于400个音乐时，计数值N增加。此外，在随机设置待机时间（Tp）之后，重复FET（Q1）的接通。当计数值N达到7时，IC电路51-1的FET（Q1）保持在截止状态。因此，仅能够停止发生死极的负载驱动电路，并且可以继续驱动其他负载驱动电路。
