I agree, although power is also quite well managed in USB PD since both devices know what is supposed to come in, the cheapest chip that I found from TI[0] has:
> Integrated reverse current protection, undervoltage protection, overvoltage protection, and slew rate control for both 20-V/5-A power paths when configured to Sink
> Integrated undervoltage protection, overvoltage protection, and current limiting for inrush current protection for both 20-V/5-A power paths when configured to Source
Unless they really cheaped out on the charging chip there should be no reason to restrict it.

I'm not an expert on semiconductor market segments, but it's possible that TI occupies the high end segment, so even their cheapest chips are feature packed. Therefore whatever the cheapest chips they put out isn't really a lower bound in terms of quality. You could still have random chip makers from china that make even worse chips.
- f_devd 4y agoTrue, you can probably get worse chips for s better price from somewhere but these aren't particularly expensive for the devices Apple makes.
