Charger Click Board
The Charger click is an add-on board that comes integrated with two chips, one is a battery charger controller, and the other one is a battery charge monitor. The smaller chip MCP73831 is a miniature single-cell, advanced linear charge management controller that is commonly used is space-conscious and budgeted applications. This fully integrated Li-ion, Li-polymer charge management controller works with a programmable charge current from 15 mA to 500 mA. The larger chip DS2438 is a smart battery monitor, commonly used in portable computers, cell phones, consumer electronics, handheld instrumentation, etc. The board also features an on-board battery connector to facilitate connection. Charger click uses the unique 1-Wire interface, which requires only one port pin, for communication with the target microcontroller. The DS2438 has a unique silicon serial number, which allows several units to work on the same 1-Wire bus.
This permits multiple battery packs to be charged or used in the system simultaneously. It is designed to operate using a 5V power supply source.

IC/Module: MCP73831 Li-Ion and Li-Polymer Charge Management Controller
The MCP73831 is a small-sized, low-cost linear charge management controller consisting of an integrated pass transistor, integrated current sensor, and a reverse discharge protection. This single cell, fully integrated Li-Ion and Li-Polymer battery charger controller is well-suited for portable applications thanks to its small physical size and low number of external components.
IC/Module: DS2438 Smart Battery Monitor
The DS2438 is a battery charge monitor chip that comes integrated with a direct-to-digital temperature sensor that eliminates the need for thermistors in the battery pack, an ADC to measure the battery voltage and current, and an elapsed timer. It also includes a current accumulator that monitors the total amount of current going into and out of the battery, as well as 40 bytes of nonvolatile EEPROM memory for storage. .
Charger click includes a zero-ohm OW jumper that enables the user to select between two available pins for the 1-Wire interface.
