Is there a voltage limit implemented in USB A to USB C charging?

I have to assume the cable has plugs on both ends, Type-A and Type-C, and that the powerbank has a Type-C receptacle for charging. The cable is not allowed to signal any other than "default" ...

Help identifying chip in Huawei motherboard

Found the below code from here: https://smd.yooneed.one/ Seems like a voltage detector IC might make sense given the application you described. It may be something in that family

What shape should the PCB edge have for this USB connector?

There's nothing in the 3D model that clashes with the PCB without the cut-outs: - I think those cut-outs might be trying to tell you that you need to ensure there is some clearance to components or ...

What shape should the PCB edge have for this USB connector?

The cutouts are specified because the milling cutter has a non-zero radius so cannot cut a sharp inside corner. Extending the cut ensures that there will be no interference. This is a standard ...

Seeking USB-C Female PCB Connector for Razer Kraken X Headphones Adaptation

Usual solution to your problem of adapting a USB-A captive cable (as on many headsets) to a USB-C port is to buy a simple adapter like this one: No modification of any sort is needed.

Are there any techniques for soldering USB-C 16 pin?

It's very difficult to accurately apply paste on small pads with a stencil without a "paste printer" (device to do that mechanically) To solder this type of component manually, you should ...

Are there any techniques for soldering USB-C 16 pin?

Reduce the paste aperture a bit to resolve shorts The pads have a relatively large area, of which most is covered by the pins. This causes too much solder paste on the pads, which flows over and ...

Are there any techniques for soldering USB-C 16 pin?

I also often find it difficult to gauge the right quantity of paste to use, and with USB connectors, it can often be particularly annoying to rework as the pins extend under the connector. What you ...

Are there any techniques for soldering USB-C 16 pin?

Looking at the datasheet, the through-hole pins are 1.20mm long. As such, they can be problematic with standard (1.6mm) PCB thickness. I'd suggest looking for a part with longer pins, or using a ...

Why are CC1 and CC2 only connected to USB-C?

USB specs forbid it. The CC pins are used to detect if something is connected and negotiate what it is that is connected before power is applied or data communication is started. You cannot have an ...

Why are CC1 and CC2 only connected to USB-C?

CC1 and CC2 are required for communication with the charger (or other power source) in order to determine its current handling capability and/or negotiate higher power levels. You can't just draw as ...

Pulling 100W from USB-C PD through SMD connector

The current is split between four conductors, and therefore needs to be collected in parallel on your PCB too. You've made a comment that there are only two pins, but this isn't usually true - instead,...

Pulling 100W from USB-C PD through SMD connector

A very simple solution is to use a through hole connector: Source: https://gct.co/connector/usb4085 Then you can fill a solid power/GND plane each on it's own layer and obtain very low resistance. ...
