说明

TPS23525 是一款集成式热插拔双路 OR-ing 控制器,可使大功率电信系统符合严苛的瞬态要求。该器件具有 200V 的绝对最大额定电压,因此可轻松通过雷击浪涌测试 (IEC61000-4-5)。借助软启动电容器断开功能,可通过限制浪涌电流来使用较小的热插拔 FET,而不会影响瞬态响应。400µA 拉电流支持快速恢复,有助于避免雷击浪涌测试期间的系统复位。借助双路限流功能,可轻松达到 ATIS 0600315.2013 等标准所规定的掉电和输入阶跃要求。最后,该器件还可提供带可编程阈值和迟滞的精确欠压和过压保护。

TPS23525 集成有双路 OR-ing 控制器,因此非常适合用于由两个冗余电源供电的 –48V 系统。
