Still on the topic of the USB charger… I ordered some samples from TI for some various components:
- TPS2561A dual-channel current-limited switch
- TPS2513A dual-channel dedicated USB charging port controller
- TPD2E001 ESB protector
TI was gracious enough to ship some samples to me. (I also ordered a demo board with all these components mounted so I can conduct some experimentation)
I’m glad I ordered the demo board.
Upon looking at the chip, I’m realizing I need some new tools. I knew I needed a new soldering iron — now I know I need a microscope as well.
The dimension’s of this chip are 3.1mm square. The “pins” are on 0.5mm centers with each pin nominally 0.25mm wide (0.18mm – 0.30mm actual)
Yeah. I think I need some visual enhancement.
