The Texas Instruments bq2403x family of linear charge regulators were originally designed to charge single-cell Li-ion batteries from an AC adapter or USB port. However, these ICs also lend themselves well to applications powered by solar panels. - Dynamic Power-Path Mgmt & Dynamic Power MgmtPDF, 96 Kb, File published: Jan 2, 2007
Dynamic power-path management (DPPM) and dynamic power management (DPM) are two similar types of integrated power management ICs that combine the task of charging a single-cell Li-ion battery and powering the system. Both topologies reduce the battery charging current to give the system priority when the adaptor has reached its output current rating. The bq2403x family and TPS65800 IC use the DPP
