The The MikroElektronika's Charger 16 Click is a compact add on board that represents a single cell battery charger. This board features the LT1571, a constant-current or constant voltage battery charger with preset voltage and termination flag from Analog Devices. Powering up from an external power supply rated up to 20V, this Click board has an on board current sense resistor which allows simple charge current programming to within 5% accuracy. The internal switch is capable of delivering a 1.5A DC 2A peak current. It also comes with an indication for battery near full-charge state, when the charge current drops to 20% of the programmed value, and selectable constant voltage for 4.1V or 4.2V per cell with 0.6% accuracy. This Click board is suitable as a Li ion, NiMH, NiCd battery charger for portable devices and accessories, power tools, and more.
