This reference design contains highly integrated single cell Li-Ion battery chargers targeted for space-limited, portable applications with high capacity batteries. The solution includes a single cell charger with a single input that operates from either a USB port or AC wall adapter for a versatile solution. BC1.2 compliant D+/D detection allows for recognition of CDP, DCP, SDP, and non-standard USB adapters. The use of an accessory dead battery provision (DBP) pin allows for the system to sync a dead battery state in order to enable/disable the BC1.2 detection in the case of an external USB-PHI. The user's guide includes board specifications, the schematic diagram, bill of materials, and board layout.
