Help with usb board

[sonik-br]

Hi,

My USB board is busted. The component over the U2a (NCP380LSNAJAAT1G) is burned and I can't find another to buy.
There's any equivalent component that will work?

option 1: you may disable VBUS control, so you won't need this chip. USB devices will have permanent 5V supply from main power. Refer to schematics and notes there.
option 2: there are no equivalents. There is only version for uDFN6 case of the same chip which may hold slightly higher current than busted TSOP6 version.

Thanks for the answer.

I'm a layman in electronics .

What's the purpose of VBUS? If I get it right, it's to power on/off the usb hub in sync with mister's main board?

For option 1 I can just bridge the JP3? JP1 too?
It will drain power from the mister's usb or from external psu?

it allows USB host controller to turn power on/off of USB devices.

Short JP1. JP3 doesn't matter.

It will drain power from the same source as with VBUS control.

My board is dead. Even without VBUS. Power works but no data.
I've got a new one :)
