iW632
RapidCharge™ Dedicated Charging Port Controller for
Qualcomm® Quick Charge™ 2.0 and Divider Mode
1 Description
The iW632 is a RapidCharge™ Dedicated Charging Port (DCP) controller for Qualcomm® Quick ChargeTM 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 (MDs), 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 MD. 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 over-voltage, and fault and reset signals.
In addition, iW632 also implements proprietary D+/D- over-voltage 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.
Dialog’s innovative proprietary technology ensures that power supplies designed with the iW632 can provide multilevel output voltage configuration, smooth voltage transition and ultra-low no load power consumption.
