Charger 5 click is designed to charge Lithium-Ion and Lithium-Polymer batteries. Besides the overvoltage and undervoltage protection, reverse discharge and overtemperature protection, automatic recharge and end of charge safety timer, the click also introduces the fast charging feature to the line of click board™ charger products. Charger 5 click uses a programmable digital potentiometer for adjusting the fast charging constant current, which can be set from 100 mA to 950 mA, via the SPI interface.
Charger 5 click carries the MCP73113, a single-cell Li-Po/Li-Ion battery charge IC from Microchip, along with the digital potentiometer chip labeled as MCP4161, from the same company. This click can be used to easily and securely charge and fast-charge batteries on many different devices that use 3.7V Li-Po/Li-Ion batteries.
