Reviewing MCP73832 Li-Ion Charger and MIC5305 LDO for 3.3V USB Battery Supply

Hi,

I would like to ask you for advise and correction in case it is wrong. I wanted to change this power supply by usb which is working rightly in my device http://i.imgur.com/wRttv6c.png to one using lion/lipo batteries.

So I did this schematic http://i.imgur.com/aBNC1c0.png using http://www.micrel.com/_PDF/mic5305.pdf and http://datasheet.octopart.com/MCP73832T-2ACI-OT-Microchip-datasheet-16123459.pdf

What do you think about it? Will it protect enough my batteries? Do you see any mistake or something could be improved?

Thank you!

Thank you Colin, but i need the design to integrate it in a PCB.

Hi again,

I changed my schematic again to this one

This schematic is divided in 2 parts. From LiPo to right is based in my current schema powered only by USB 5V. And LiPo to left is what i added based on this design

So, having this all together, do you think is there any error? Should I put any component between these two schematics? I am specially worried about when the battery is full.

Thank you
