RT9745A

双通道, 低阻值负载开关

RT9745A
New

RT9745A 是一个具有致能脚位、小体积、超低 RON 的双通道负载开关。产品内含两个 N-MOSFET，可操作在输入电压范围从0.8V至5.5V，且单一通道最大电流可输出6A。每一个开关皆独立由致能脚位(EN1和EN2)控制，可直接和低电压控制讯号连接。RT9745A 提供WDFN-14TL 3x2 封装。

应用

    ► RON = 27mΩ at VIN = 1.8V (VDD = 5V)

  • 每通道6A 最大连续开关电流

  • 低静态电流
    ► 75μA (双通道)
    ► 55μA (单通道)

  • 启动电压最低可以使用 1.4V/1.8V/2.5V/3.3V

  • 可配置的上升时间

  • 快速输出放电 (QOD)

  • 自适应放电电流

  • 14T引脚WDFN封装与散热垫
