The FSA832L10X is a charger detection IC with an integrated isolation switch for use with micro/mini USB port. The FSA832L10X detects USB battery chargers and is compliant with USB Battery Charging Specification, Rev 1.2 (BC1.2). The FSA832L10X also detects proprietary chargers that pull the USB data lines HIGH (2.7 V / 2.0 V), floating data lines, and PS/2 ports. The device determines if a charger, either through a Dedicated Charging Port (DCP) or Charging Downstream Port (CDP), is connected or if a typical PC host, a Standard Downstream Port (SDP), is connected. The FSA832L10X conforms to all the constraints for the Dead Battery Provision (DBP) within the BC1.2 specification, including a 30-minute timer that cannot exceed 45 minutes per BC1.2.
