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. 2 Features ●● Supports Qualcomm® QC2.0 High Voltage Dedicated Charging Port (HVDCP) Class A with voltage configuration of 5V, 9V, and 12V ●● Supports divider mode with D+/D- at 2.7V/2.0V for 2.1A rapid charging ●● ●● ●● ●● ●● Proprietary D+/D- OVP and proprietary Dimpedance detection address soft short issues in the output cables and connectors and provides protection against damages ●● Programmable active fast discharge from 9V/12V to 5V at MD unplug or from a high voltage level to Optionally supports Samsung Adaptive Fast Charging a lower level upon request with built-in switch or (AFC) for output voltage and current negotiation external switch Backward compatible with USB Battery Charging ●● Normally OFF state with <120µA cut-off current Specification Revision 1.2 (USB BC1.2) DCP during 5V steady-state operation to achieve ultra-low power consumption at no load Backward compatible with Chinese Telecom Standard YD/T 1591-2009 Shorted Mode ●● Wide operating voltage range from 3V to 25V Automatically differentiates MDs and determines rapid charging protocols 3 Applications ●● DC/DC converters/chargers for smart phones, tablets, and other mobile devices Qualcomm® Quick ChargeTM 2.0 is a product of Qualcomm Technologies, Inc.
