Charging multiple devices with a simple 5V power supply

[Erwin Ried]

Hi! I want to charge several USB devices with a simple power supply (the usb devices connected in parallel to the supply and the D+ and D- can be shorted with a switch for tablets that assume that is 1.5A not 0.5A supply), should I have something (electric) in consideration?

It would work.

Ideally, you would get some charging controller ICs that auto configure the data wires for you , going through multiple configurations of signals on those data wires and auto detecting the right way to get your device power at max speed.

For example see TPS2514 (single)  or TPS2513 (dual)

TPS2514 : https://www.digikey.com/product-detail/en/texas-instruments/TPS2514DBVR/296-39376-1-ND/5143327

TPS2513 : https://www.digikey.com/product-detail/en/texas-instruments/TPS2513ADBVR/296-39375-1-ND/5143326



The footprints are the same, the TPS2514 simply doesn't have two pins connected to anything.
They're surface mount, but should be fairly easy to solder by hand ... for example you could just bend the middle pins (input voltage and ground downwards) and the side pins (data+ and data- for each usb port) upwards to increase distance between pins and then you could simply solder thin wires to each lead.
You can also get adapter boards : https://www.ebay.com/itm/SOT23-6-SOT457-Breakout-Board-Adapter-for-Prototyping/202474684418

Thanks! I though on using something like that but I took appart a lenovo usb supply and it just shorted them out 😂😂 but the v+ and gnd, they dont require diodes or anything? The supply I have is enough so I am thinking if something can happen between devices that needed my attention
