摘要
文中介绍可实现瞬变过压、非瞬变过压、过流和电源反接保护的电源保护电路,采用自恢复保险丝和LTC1696为主要器件。根据输入电压的不同,电源保护电路稍有不同。该电路简单可靠,适用于输入工作电压低于60VDC的各种应用场合。
The power source protection circuit that can implement instantaneous over voltage, coinstantaneous over voltage, over current protection was introduced. It adapts self recovery fuse and LTC1696 as main component. The protection circuits are varied according to the input voltage. The designed circuit is suitable to 60VEX2 input.
