The iW632 is a RapidCharge™ Dedicated Charging Port (DCP) controller for Qualcomm® Quick Charge™ 2.0 (QC2.0) technology, optional Samsung Adaptive Fast Charging (AFC) and divider mode USB interface. It allows rapid charging of QC2.0 or divider mode enabled mobile devices, and it automatically identifies QC2.0, AFC and divider mode protocols. The iW632 resides on the USB port of the power adapter and allows the adapter to be configured for multi-level output such as 5V, 9V or 12V depending on the voltage requested by the mobile device.
It can be used in DC/DC power converter systems to achieve smooth voltage transition and low no-load power consumption. The iW632 implements three output pins for output feedback ratio change, output overvoltage, and fault and reset signals. In addition, iW632 also implements proprietary D+/D- overvoltage protection (OVP) and proprietary D- impedance detection to address soft short issues in the output cables and connectors that can be caused by such things as a poor or loose connection between the cable connector and the socket, contamination in the USB connector, or a worn-out cable, and provides protection against the damages.
