Description
The FSA832 is a charger detection IC with an integrated
isolation switch for use with micro/mini USB port. The
FSA832 detects USB battery chargers and is compliant with
USB Battery Charging Specification, Rev 1.2 (BC1.2).
The FSA832 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
FSA832 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.
