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：提供了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微秒时，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。

摘要： A field effect transistor is provided between the ground and an H bridge circuit for rotating a motor in forward and reverse directions in a manner that the drain of the transistor is grounded and the gate thereof is coupled to a DC power source such as a battery serving as a bias source which supplies electric power to the H bridge circuit. Thus, when the DC power source such as a battery is reversely connected, the field effect transistor normally in an on state is turned off. A controller monitors the source voltage of the field effect transistor, and when the controller detects an excess current, the controller outputs a control signal to the high-side driver to prevent the supply of electric power to the motor.
