How is this SparkFun charger capable of charging a LiPo at the same time as powering other devices? The Set up would look like this:
This is what the schematic looks like. Basically, my confusion is that the MCP73831 needs to provide current to the battery to charge it, but if you look at the schematic, the VBAT output of the chip is directly connected to the SYS_OUT and BATT_IN headers. This is confusing because it means that the chip is technically providing current to BOTH the device connected to SYS_OUT and the battery? Isn't this a bad thing? Why would I want to provide current to my output device with a LiPo charging profile? Couldn't this ruin things? Also, doesn't it take away from the battery being charged?
