Battery charge self? #58

Review the MCP73831 datasheet. The battery is connected to VBUS through a diode. Will the MCP73831 try charging the battery if the system is on battery power? If so, add a switching circuit like what is on the T400.

From the MCP73831 datasheet. The input voltage much be 150 mV above the battery voltage for the MCP73831 to become operational screen shot 2016-09-13 at 19 30 05
