摘要： A system comprising first and second redundant controller modules, each controller module comprising mode management circuitry configured to identify whether the corresponding controller module operates in a master mode or a slave mode. The mode management circuitry in each controller module is configured to couple to the mode management circuitry in the other controller module. The mode management circuitries in the controller modules are configured to collectively operate so that one of the controller modules is assigned the master mode and the other of the controller modules is assigned the slave mode. At least one of the mode management circuitries in the controller modules is configured to assign the master mode to the corresponding controller module based on a takeover signal when the mode management circuitry in the corresponding controller module is ready for use.

摘要： An input protection circuit for protecting components of an input circuit. The input protection circuit includes a resettable fuse that functions as a current limit integrated circuit to maintain a maximum current so that the circuit can function in a normal operating range with less current. A Zener diode can measure the circuit's voltage and control a metal oxide semiconductor field-effect transistor (MOSEFT) to avoid impact with the analog signal input. The MOSEFT is open if a voltage input is less than a Zener diode breakdown voltage. The Zener diode breakdowns the current flow directly into a ground via the MOSEFT if the voltage input is higher than the Zener diode breakdown voltage. The resettable fuse will shut down until the resettable fuse is reset if the current is higher than the resettable fuse trip current. The protect circuit restarts after the resettable fuse is reset.
摘要翻译：一种用于保护输入电路组件的输入保护电路。输入保护电路包括可复位保险丝，其用作限流集成电路以保持最大电流，使得电路能够在较小电流下工作在正常工作范围。齐纳二极管可以测量电路的电压并控制金属氧化物半导体场效应晶体管（MOSEFT），以避免与模拟信号输入的冲击。如果电压输入小于齐纳二极管击穿电压，MOSEFT将断开。如果电压输入高于齐纳二极管击穿电压，则齐纳二极管将电流通过MOSEFT直接击穿到地。如果电流高于可复位熔断器跳闸电流，则可复位保险丝将关闭，直到可复位保险丝复位。保护电路在可复位保险丝复位后重新启动。
