The Great Search: Simple Resistor-Set Lipoly Charger Chip

Adafruit Industries

This week we worked on some Picowbell designs, including a prototyping plate that includes a battery charger. We recycled charging and switch-over designs from our Feathers but then we realized we never showed off the charger chip itself! We tend to use the MCP73831, but there's approximately 4902 different variants! Let's take a look at how to select a charger that matches your battery: voltage and charge rate are the biggest things to check. There's also other extras like LED indicators, time-outs, and load-sharing/prioritization.
