说明 (续)

当上行端口连接到一个仅支持全速/低速连接的电气环境中时,下行端口上的超快速 USB 和高速连接将会禁用。

TUSB8043A 支持每端口或成组电源开关和过流保护,并且还支持电池充电 应用中节省电路板空间。

按照 USB 主机的要求,通过端口电源单独控制集线器开关为每个下行端口上电或者断电。另外,当端口电源单独控制集线器检测到过流事件时,仅关闭受影响下行端口的电源。

当需要为任一端口供电时,一个成组集线器开关打开到其所有下行端口的电源。只有当所有端口处于电源可被移除的状态时,到下行端口的电源才可被关闭。另外,当端口电源单独控制集线器检测到过流事件时,会关闭所有下行端口的电源。

TUSB8043A 下行端口可提供电池充电下行端口 (CDP) 握手支持,以此为电池充电 应用 提供支持。在未连接上行端口的情况下,该器件还支持专用充电端口 (DCP) 模式。DCP 模式适用于支持 USB 电池充电、Galaxy 充电和符合中国电信行业标准 YD/T 1591-2009 的 USB 器件。 此外,在未连接上行端口的情况下,TUSB8043A 支持分频器充电端口模式(ACPx 模式),并且可在所有模式之间进行自动切换,切换顺序从 ACP3 模式开始,到 DCP 模式结束。

TUSB8043A 能够为包括电池充电支持在内的部分 特性 提供引脚搭接配置,还能够通过 OTP ROM、I2C EEPROM 或 I2C/SMBus 从机接口为 PID、VID、自定义端口和物理层配置提供定制支持。使用 I2C EEPROM 或 I2C/SMBus 从机接口时,还可以提供定制字串支持。

TUSB8043A 通过内部 USB HID 和 I2C 接口支持连接的 EEPROM 编程。

该器件采用 64 引脚 RGC 封装,商用版 (TUSB8043A) 的工作温度范围为 0°C 至 70°C,工业版 (TUSB8043AI) 的工作温度范围为 –40°C 至 85°C。
