TUSB212: TUSB212

Part Number: TUSB212


HI Team,

i would like to check whether TUSB212 can support input signal hot-swap function.

In my customer test, they found after power up, the TUSB212 can work normally and compensate the signal loss. But after reconnecting the input signal cable, the compensation doesn't work any more unless we do a manual reset by the RSTN pin. Is that normal? Thanks.

    Hi Hollis,

    That is not expected.  Does the USB connection restart during this disconnect / reconnect?  Can you probe the CD pin and the ENA_HS and check the status when the TUSB212 is not compensating?

    Thanks,
