LiPo Charger/Booster for 3.7V Single Cells, micro-USB US$19.95

PRT-10300
LiPo Charger/Booster for 3.7V Single Cells, micro-USB


The PowerCell board is a single-cell LiPo boost converter (to 3.3V and 5V) and micro-USB charger in one. The board comes with a JST connector for a single-cell Lithium Ion or Lithium Polymer battery, a micro-USB connector for the 5V charge input, and selectable 3.3V and 5V ouput pins (labeled out). There are also two charge pins broken out (labeled charge) so you can use another 5V power source to charge the batteries if you don't have a micro-USB cable.

The micro-USB charger uses the Microchip MCP73831T-2ACI/OT and allows you to charge 3.7V LiPo cells at a rate of 500mA.

Instead of requiring a PC's USB power, you might consider the TOL-11456 wall-mount 5V, 1A power supply that uses a USB cable for delivery.

The boost converter is based on the Texas Instruments TPS61200 and has solder jumper selectable 5V and 3.3V output, and an under-voltage protection of 2.6V.

Note: This board does not have reverse-polarity protection. Be sure of the polarity of your connections!
