说明

TPS2595xx 系列电子保险丝(集成式 FET 热插拔设备)是小型封装内高度集成电路的保护和电源管理解决方案。这些设备只需很少的外部组件即可提供多种保护模式,能够非常有效地抵御过载、短路、电压浪涌和过多浪涌电流。

输出电流限制级别可通过单个外部电阻设定。还可能通过测量整个电流限制电阻的压降实现对输出负载电流的准确感应。对 浪涌电流有特别要求的应用可以通过单个外部电容器设定输出转换率。过压事件由内部钳位电路快速限制在一个安全的固定最大值,而无需外部组件。TPS259573 型号提供可以设置用户定义过压截止阈值的选项。

在 TPS2595x5 型号中,可通过将 OUT 引脚连接到 QOD 引脚实施快速输出放电功能。

这些器件的独特运行温度范围为 –40°C 至 +125°C。
