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
