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.
