So I’m an absolute newbie and only an electronics hobbyist. I’ve been soldering for years, mostly modifying/repairing video game consoles. Inspired by the guys over at bitbuilt I recently decided to try and build a handheld PlayStation 2. The plan is to power it with 4x 21700 cells wired in series. I’d also like to charge (and charge while playing) through USB-C power delivery. I’ve purchased this charging management board to handle all my battery protection and charging, and if I’m not mistaken it will deal with charge-and-play. (By charge-and-play I mean that it will disconnect the battery from the load and power the console directly from the power supply when plugged in while allowing remaining power to charge the batteries). I also have the parts to handle all the voltage regulation I should need in the mail.
I’m trying to design a circuit that does the following things:
1. allows charging using USB-C PD. IE will communicate with a USB-C charger to trigger 5v voltage delivery for charging.
2. Has a USB female port that will house a small internal USB drive where game files will be stored. I want to be able to access the drive through the USB-C port when the device is off and I want the port to be routed to the motherboard when the device is on. From my understanding this should be handled by a USB multiplexer.
3. Possibly manages charging/protecting my 1s battery pack as well as “charge-and-play” if the board I bought off Amazon looks insufficient.
My problem is primarily that I don’t have any idea where to even start, which likely means I’m biting off more than I can chew. Using my limited ability to source ICs to accomplish what I want I’ve come across some TI devices like this one that appears to have the ability to meet my PD and mux needs. I just wouldn’t know where to begin designing a PCB to utilise this thing.
I guess my overarching question is this: Is such a thing far too complex to design for someone with no background? If not, what are some resources I could use for reference circuits/understanding how any of this works?
Thanks in advance for any wisdom.
