说明

TPS2660x 器件是一系列功能丰富的紧凑型高电压电子保险丝,具有一整套保护 功能)。4.2V 至 60V 的宽电源输入范围可实现对众多常用直流总线电压的控制。器件可以承受并保护由高达 ±60V 的正负电源供电的负载。集成的背靠背 FET 提供反向电流阻断功能,因此器件非常适合在电源故障和欠压条件下要求保持输出电压的系统。该器件还具备许多可调功能,可提供负载、电源和器件保护 功能 包括过流保护、输出转换率和过压保护以及欠压保护。TPS2660x 内部可靠的保护控制模块以及高耐压值有助于简化针对浪涌保护的系统设计。

借助关断引脚,可以从外部控制内部 FET 的启用/禁用,还可以将器件置于低电流关断模式。为实现系统状态监视和下游负载控制,器件提供故障和精密电流监视输出。MODE 引脚有助于在三个限流故障响应(断路器模式、闭锁模式和自动重试模式)之间灵活地对器件进行配置。

器件采用 5mm × 4.4mm、16 引脚 HTSSOP 封装和 5mm x 4mm、24 引脚 VQFN 封装;额定温度范围为 –40°C 至 +125°C。
