Availability date:
Here is a charger for Lithium Ion and Lithium Polymer battery based on the MCP73833. It uses a USB mini-B connector to charge the battery from any computer or USB power supply. Charging takes place in three steps: the first precondition the charge, then the fast charge with constant current and finally the battery is maintained at maximal charge (maintenance charge) using a constant voltage charge. The fast charging is done with a current of 500mA (default) but can be adjusted between 100mA and 1000mA by welding a suitable resistance on the card.
Thanks to its 3 LEDs, this card is particularly suitable for hacking/DIY projects. There is one LED to indicate the power supply of the card (identified as PWR), another indicates the charging status (identified as CHRG) and a last indicating when the charge is complete (identified by DONE).
Connect the battery to the BATT connector. You can then consume the battery energy using a load (your circuit/project) that you connect to the LOAD connector using the JST plug included.
Since your project and your battery are connected to the charging card, you can use your battery without disconnecting it from the charger to connect it to your project. Best of all, you can charge your battery by plugging the card into a USB port (or via DCIN) without having to unplug your project!
This charger can only be used with our Lipoly battery! The other batteries use other voltage, chemical composition, polarity, pinning.
Battery and USB cable not included.
