Charger 9 Click Board

The Charger 9 Click Board™ is a Li-Ion (Li+, Li-Po) battery charger, capable of charging one, two or three battery cells. It is based on the MAX1757, an integrated Li+ battery charger with many features that allow safe and reliable charging. This IC has an internal switching-mode regulation with input current limiting, allowing it to use an external power supply from a cheap wall adapter, rated up to 14V. An extensive state machine of the MAX1757 IC with two additional timers regulates the charging process, ensuring a safe and reliable battery charging process. In the case of an error, the charging process is stopped, and the fault is reported both over the LED and over the mikroBUS™ pin.
