This reference design is highly integrated stand-alone Li-ion and Li-polymer switch-mode battery charge solution with two integrated N-channel power MOSFETs and a power path selector gate driver. It offers a constant-frequency synchronous PWM controller with high accuracy regulation of input current, charge current and voltage. It also provides battery detection, pre-conditioning, charge termination, and charge status monitoring. The reference design is also called the HPA715 (-001). This solution is optimized for a 5V input voltage and charges a single cell 4.2V Li-ion battery.
