The FSA832 is a charger detection integrated circuit with integrated isolation switch for micro/mini USB ports. The FSA832 detects USB battery chargers in compliance with the USB Battery Charging Specification Rev 1.2 (BC1.2). The FSA832 also detects proprietary chargers, pulling USB data lines high (2.7 V / 2.0 V), floating data lines and PS/2 ports. The device determines if a charger is attached through a dedicated charging port (DCP) or charging downstream port (CDP), or if a common PC host, standard downstream port (SDP), is attached. The FSA832 complies with all constraints of the Dead Battery Clause (DBP) of the BC1.2 specification, including the 30-minute timer specified by BC1.2 cannot exceed 45 minutes.
