说明

MAX3453E–MAX3456E带±15kV ESD保护的USB兼容收发器可将低压ASIC连接至USB设备。这款器件工作在全速(12Mbps)或低速(1.5Mbps)时,完全符合USB 1.1和USB 2.0规范。MAX3453E–MAX3456E可工作在低至+1.65V的VL下,保证与低电压ASIC的兼容性。

MAX3453E–MAX3456E具有逻辑可选的挂起模式,电流消耗可减少至40µA以下。内部集成的±15kV ESD保护电路为USB D+和D-双向总线连接提供了保护。

MAX3453E仅支持全速(12Mbps)工作模式,MAX3453E/MAX3454E内部有一个1.5kΩ的USB上拉电阻和枚举功能,该功能允许将插入的设备逻辑上断开。MAX3453E/MAX3455E提供了一个推挽式总线检测(BD)输出,当VBUS高于+4.0V时输出高电平信号。

MAX3453E-MAX3456E工作于-40°C至+85°C扩展级温度范围,采用14引脚的TSSOP和16引脚(3mm x 3mm)薄型QFN封装。
