In this episode of DIY or Buy we will have a closer look at a USB Type-C Power Delivery Trigger board. Such boards are used to output 5V, 9V, 12V, 15V or even 20V from a Power Delivery compatible power source. So I will be showing you how such a commercial board works and I will try to create my own DIY version of it in order to see whether it makes sense to DIY such a board or whether we should stick to the commercial solution instead. Let's get started!

USB PD is the best thing since sliced heatshrinks. I've been using it on most of my projects and the convenience is real.

@GRBtutorials 4 года назад

Wait, sliced heat shrinks? That exists?

@@GRBtutorials I think it's a joke on the anglophonic advertisement adage “best thing since sliced bread”. Which I've never understood. How are people incapable of slicing their own bread? Sliced bread has a shorter shelflife.

I'm not joking, they do exist. Just search as "heatshrink kit" and there are variety of them to choose. And as being the parody of "sliced bread", well that was my intention too but pre-cut heatshrinks are really convenient to use for me.

@ketandesai5326 4 года назад

I suggest TVS diodes on those CC pins. You want to try avoid large transients on cable removals

@Sverbog 4 года назад

Could you elaborate what would cause the large transients? And why diodes would help that

@ketandesai5326 4 года назад

LC Raz When you unplug the cable, there is a spike in voltage. This is due to the storage of energy in reactive elements of the circuit. An example would be an inductive load, when you unplug it the magnetic field rapidly breaks down and induces a high voltage. A TVS diode works by depending on the voltage to exceed its breakdown voltage. Essentially when the Spike exceeds the breakdown voltage of the diode, the diode will shunt to ground.

@crenn6977 4 года назад

@FQD2N There is inductance everywhere, it might not be big, but it's there. Just because it's not on a cheap aliexpress board, doesn't mean it's not a good idea to have it. External interfaces (even USB connectors) should have some ESD protection minimum. TVSs are one way of doing that.

@jawwadsabir4620 4 года назад

LC Raz built-in transistors serve the same purpose.

@nullptr4042 4 года назад

@FQD2N see this guide www.ti.com/lit/wp/slyy105/slyy105.pdf?ts=1592861588015 from TI. You can also checkout the datasheet for a reputable USB PD implementation like the stusb4500qtr chip which includes protection for this type of thing in the typical application example. The circuit designed in this video is a very naive implemenation

If the pin is grounded, it will only output 5V

Diy would be the preferred method though in instances where you already are using a microcontroller for something else and needed power negotiation (eg in something like a soldering station for a TS 100 iron). If you have a specific use case where going the diy route will reduce part count it could definitely be worth it.

@aisawaloki1571 3 года назад

Thank you so much as I am searching for similar guidelines so far. And occasionally your this video solve my mystery failed similar attempt before: I mixed up between CCs and SUBs pins of the very same USBC female connector you are using... Thanks a lot again! p.s. 0:52 PD would in fact not deliver any power at all, neither the most basic 5V, if your device does simply only connect to the VBUS and GND pins, i.e. connect a non-USB-C device with a USB PD sink via passive adapters. This is because while VSUB of other type-A based fast charging (as well as legacy USB) would always have at least 5V, a compliance USBC PD source would instead have no voltages (or so called "high impedance") until it detected something is connected, by detecting if either one CC pin is pulled down by the sink, which is pulled up by the source itself. As non-USB-C does not have CC pins as all it do not "power up" any PD sources.

@gideonzweijtzer8784 2 месяца назад

This is really a great video; thank you! I am planning to power a board with USB-C PD, and since the board power control is done with an ESP32 (which also allows OTA firmware updates and much more), it would be most convenient to buy an integrated solution, like CK224K. The issue there is, that it doesn't provide any status, so the only way to know if the triggering worked is to measure the voltage with an ADC input. It is not very convenient. Retargeting the PD software to ESP32 shouldn't be too difficult and gives much finer control. Plus, I can still use the D+/D- lines to reprogram the ESP32. In order of cost, I think the CK224K is about $0.60/pc @ 1000, and the FUSB302 is about $0.50/pc @ 1000. Then of course, there is the CYPD3177, but that one creeps closer towards $1/pc. I am still in doubt which part to use.

If you want to inspect the USB PD protocol, I recommend the AVHzY CT-2. It's mainly used for triggering and measuring power draw (which it's fantastic for) but it'll also enumerate all the available power levels and connect to desktop software to show you all the messages going back and forth. Super handy, I used it for evaluating ~30 power banks. Also a minor nit: USB-PD isn't only for USB Type C. PD 1.0 works with micro-USB and type A/B. PD 2.0 is the main one you're a fan of I think, with the separate config channel on the Type C connector.
