Smartphones and other handheld equipment with 3AHr+ 1S Li-Ion batteries require 3-A+ charger current for fast charging. Parallel chargers allow for high charge currents, resulting in shorter charge times, while distributing the heat losses across the end equipment PCB, thereby preventing hotspots. In cascade configuration, with PMID pin of master charger connected to VBUS of slave charger, input current limit management is handled through the master charger, thereby simplifying software development.
