Part Number: TPS2560
Other Parts Discussed in Thread: TPS25221, TPS2062C, TPS2065C

Hello,
i would like to use the low active TPS2560 as USB3.0 Powerswitch.

My Problem ist that the TPS2560 has an Maximum low Signal of 0,66V. My USB3.0-Host Controller is the VIA VL805 which has an Maximum Vil of 0,8V. (Vih 2V).

Is there any Texas Component wich preferes higher Signals as low Signal ??

Hello Bob,

thank you for the answer but in the datasheets I could see that both have:
Vil(EN) : max. 0,66V
VhL(EN):min 1,7V

the Via chip produces Vil max. 0,8V so that could make Problems in this case ?

Mario
