Part Number: TUSB9261
Other Parts Discussed in Thread: TUSB8042,

Hello Team,

I have the following Question for a embeded product:

I don't need the TPS2001 between TUSB8042 and TUSB9261.

Can be connect the PWRCTL from TUSB8042  to USB_VBUS from TUSB9261 with a divider 47k5 / 10K (~570mV on USB_VBUS pin)?

I don't found the input current for USB_VBUS in the datasheet?

I found only the voltage for USB_VBUS = max1,155V (Capter6.3). 

The PWRCTL from TUSB8042 can drive with max current +-250µA at 3,3V(Capter7.5).

Best regards,

Iliya

    Hi Iliya,

    Yes, that will work.  We have done this on other applications.  Make sure you do not have any pullups on the PWRCTL signal from TUSB8042 that would enable battery charging.
