Texas Instruments TPD3S0x4 限流开关& ESD 保护器件
德州仪器 TPD3S0x4 限流开关& ESD 保护器件是集成式器件，包含一个限流负载开关和一个基于双通道瞬态电压抑制器(TVS) 的静电放电(ESD) 保护二极管阵列，适用于 USB 接口。TPD3S0x4 器件适用于可能出现大电容负载和短路的应用，如 USB 接口；TPD3S0x4 提供短路保护和过流保护。当输出负载超过电流限制阈值时，TPD3S0x4 通过在恒定电流模式下运行即可将输出电流限制在安全水平。快速过载响应特性有助于减轻 5V 主电源的负担，当输出短路时可以快速调节功率。电流限制开关的上升和下降时间受到控制，以尽量减小器件开关过程中的浪涌电流。
