TUSB2046 EEPROM

Other Parts Discussed in Thread: TUSB2046B

如果使用TUSB2046不外接EEPROM,EECLK和SUSPND  NC,EEDATA/GANGED 和EXTMEM拉高,将4个VRCUR全部上拉以及4个PWRON全部NC这个是否可行?

  • 不接EEPROM,EXTMEM拉高disable EEPROM, EECLK和SUSPND为输出接口,悬空即可。

    EEDATA/GANGED这个引脚用作GANGED功能 ,高电平或低电平都没问题,If GANGED is high, all PWRON outputs switch together and if any OVRCUR is activated, all ports transition to the power-off state.

    If GANGED is low, the PWRON outputs and OVRCUR inputs operate on a per-port basis.

    如果OVRCUR和PWRON不和外部Power IC连接的话,可以直接NC。

    另外,TUSB2046已经停产,建议使用TUSB2046B来替代。 并且也提供了自供电和总线供电的两种电路图,可直接参考。

  • 您好,采用了EEPROM方式,EEPROM需要烧录什么文件吗?现在没有烧录任何文件,HUB无法识别.
