I'm converting one of my old projects to instead of using non rechargables, to use LiPo batteries. To save space, I'm only using a single cell, and don't have room for a pre baked solution to handle the battery.
I need to be able to use the unit, while charging. For that, I followed the guidance found here, using the MCP73831.
For this project, I have to power a LCD display, which uses a nominal voltage of 5v, so I have to boost the voltage. For that, I used a the LiPower unit as a guide, found here. That uses the TPS61200 for the controller.
I have never designed a LiPo charging unit, let alone one that has to boost the voltage. If you could take a look at my schematic and make sure nothing is messed up I would really appreciate it.
I am using "CR-AA" as the LiPo (Will change to proper symbol when finished)
I try not to ask such a broad question, but i'm nervous about this, since there's a lot to go wrong when using a LiPo.
