利用凌力尔特的产品系列LTC4225、LTC4227和LTC4228,通过控制外部N沟道MOSFET,为两个电源轨实现了理想二极管和热插拔功能。这些器件提供快速反向断开、平滑电源切换、有源电流限制以及状态和故障报告功能,同时,还具有严格的5%电路断路器门限准确度和快速响应电流限制,可保护电源免受过流故障影响。
With Linear Technology’s LTC4225, LTC4227, and LTC4228 product families, the ideal diode and hot-swap capability is achieved for both power rails by controlling external N-channel MOSFETs. These devices provide fast reverse open, smooth power switching, active current limit, and status and fault reporting with tight 5% circuit breaker threshold accuracy and fast response current limit to protect the power supply from over Flow failure effects.
