XinaBox PL01 Battery Power Supply Battery Charger for MCP73831, PAM2305 [PL01]; 174-3724

This xChip is a high quality power module that uses power input from a Micro USB power source to charges a 3.7v LiPo battery. The circuit pulls power from the LiPo battery and charges up the xBus unless connected to this Micro USB power source.

As a simple, efficient battery charging solution, the on-board MCP73831 LiPo battery charging IC offers a host of features such as Auto Off, Cell Preconditioning, Cell Temperature Monitoring, Reverse Polarity Protection, Status Indication and Under Voltage Protection/Brown-Out. Impressively, it's also capable of charging the battery at a rate up to 500 mA.

The equipped PAM2305 is a step-down current-mode, DC-DC converter. At heavy load, the constant frequency PWM control performs with outstanding transient response and stability. To save power and deliver the longest battery life in portables, the PAM2305 features a power-saving Pulse Skipping Modulation (PSM) mode to reduce quiescent current under light load operation.
